Abstract

PROBLEM TO BE SOLVED: To prevent an inadvertent page shift that is not intended by a designer by adding a page shift rule, showing a shift originating page whose shift is permitted to its destination, to a page of its shift destination as a page shift check template statement. SOLUTION: When a page property editing processing is requested by a user, an optional shift destination page is set to a specified designation page which is set on a page shift table 113. When a page generation process is requested, a set of shift originating pages which can be shifted to certain pages is extracted from the table 113. Then pairs of shift destination pages and all shift originating pages are set on a shift rule table 114. A shiftable shift destination page is set to a page shift check template statement 117 from the table 114, and the statement 117 is added to the shift destination page.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a page transition system for displaying a plurality of pages, and more particularly to utilizing WWW resources (media information such as documents, images, sounds, and moving images) via a network and the Internet. In this case, the present invention relates to a technology that is effective when applied to a page transition system that transitions a plurality of pages in a specific order.

[0002]

2. Description of the Related Art A general WWW (World Wide Web) will be described. The WWW consists of a WWW server that provides resources (media information such as documents, images, audio, and moving images) existing on networks and the Internet, and a WWW browser that extracts the resources.

A WWW server is a program executed on a server computer. Accepts requests from WWW browsers,
Searches for the requested resource and returns it to the WWW browser. The WWW browser is a program executed on the client computer. Remotely connect to a WWW server from a WWW browser, request a specific resource, and display the resources received from the WWW server on the WWW browser.

The resources displayed on the WWW browser are HTML (Hyp
er Text Markup Language). HTML is a language that specifies page layouts and hyperlinks, and defines the syntax of dedicated built-in instructions and the location of resources. For details on HTML, see ISBN 4-900900-332-X, published on April 30, 1997, published by Ohmsha, author Stephen Spainhour, and Valerie.
Quercia, Shigeya Tanabe, book name WEBMASTER Quick Reference.

As of July 1997, many dedicated tools for creating pages have been commercialized. For example, (US) Micr
Applicable to FrontPage97 of osoft Corporation (Microsof
t, FrontPage is a trademark of Microsoft Corporation in the United States and other countries).

[0006] A conventional technique of a page transition definition method of a WWW application will be described. WWW applications are implemented as a collection of linked pages.
The pages of the WWW application are created using a text editor or the like. As of July 1997, many dedicated tools for creating pages have been commercialized. For example, (rice)
Applicable to FrontPage97 of Microsoft Corporation.

The page transition definition method of the WWW application is realized by linking a transition destination page to a created transition source page. The link structure generally forms a network structure. The network structure becomes complicated as the number of pages and the number of links increase, and it becomes difficult to determine whether the transition designed by the developer is correct.

As a technique for statically analyzing the link relation between pages, there is a document creation support device (Matsushita Information System Co., Ltd.) described in Japanese Patent Application Laid-Open No. Hei 9-81548 (hereinafter referred to as Known Example 1). ). Known example 1 describes a device that analyzes a link relationship between pages having a network structure and displays the analysis result on a screen. Specifically, it is a device that extracts a link source and a link destination of a focused page and displays the screen using a visual figure. By doing so, the relationship between individual pages can be recognized without error, and accurate page creation can be performed.

Next, a conventional technique of a page transition execution method of the created WWW application will be described. WWW
An execution example of the application is shown in FIG. The window shown on the left side of the figure shows the WWW browser executed on the client, and the flow on the right side shows the flow of processing of the WWW server executed on the server. In this example, WWW to order products
Application. In brief, the WWW application includes a page 1 for selecting a product type to be ordered, a page 2 for selecting a product to be ordered, and a page 3 for inputting a destination of the product to be ordered. The procedure will be described below.

(1) Process 2101 transmits page 1 to WWW browser 2114 (2113). After the transmission, the WWW server enters a state of waiting for a request to be received by processing 2102.

(2) The WWW browser 2114 displays the page 1 transmitted from the processing 2101.

(3) On the page 1 displayed on the WWW browser 2114, the user selects the “home appliance” radio button 2115 and then clicks the “next” button 2116 to request the WWW server for a product selection page of the selected product type. (2117).

(4) Request from WWW browser 2114 (211
7) is received by the process 2102, the following process is executed. Process 2103 is to store a product list from the selected product type in the DB
To get from. The process 2104 generates a page 2 for inputting a product and an order quantity from the obtained product list. The process 2105 transmits the generated page 2 to the WWW browser (2118).
After the transmission, the WWW server enters a state of waiting for a request to be received by processing 2106.

(5) On page 2 displayed on the WWW browser 2119, select a product from the “product name” combo box 2120, enter the number of orders in the “order quantity” text box 2121, and then click the “next” button 2122. By clicking, a request for a delivery destination input page of the selected product is notified to the WWW server (2123).

(6) Request from WWW browser 2119 (212)
When the process 2106 receives 3), the following process is executed. The process 2107 stores the selected product name and the ordered quantity. The process 2108 generates a page 3 for inputting the destination of the product. A process 2109 sends the generated page 3 to the WWW browser (2124). After the transmission, the WWW server enters a state of waiting for a request to be received by the process 2110.

(7) On page 3 displayed on the WWW browser 2125, enter the name of the orderer in the “name” text box 2126, enter the postal code in the “zip code” text box 2127, and enter the “address”. Enter the address in the text box 2128, enter the telephone number in the "Phone number" text box 2129, and click the "Order" button 2130 to send the order request for the product selected on page 2 to the entered destination to the WWW server Notify (2131).

(8) Request from WWW browser 2125 (213
When the process 2110 receives 1), the following process is executed. The process 2111 stores the destination (name, zip code, address, telephone number) of the ordered product. A process 2112 creates a product order form from the destination of the ordered product. According to the above procedure, the WWW browser can execute the WWW application while changing pages.

Further, the WWW browser has a page content recording function for storing the content of a page that has transitioned during execution, and a storage location (URL: Uniform Resource Locato) of the page that has transitioned.
It has a page storage location recording function that holds r).

The page content recording function is to store the content of a page that has already transitioned in the memory of the client computer. If you use the page content recording function, you can use the WWW browser to return to the previous page, return to the previous page, or advance to the next page,
By reloading the page stored in the memory of the client computer with the WWW browser, the page can be changed without going through the WWW server.

On the other hand, the page storage location recording function is such that the WWW browser stores the URL of the transitioned page in the memory. By specifying the URL stored in the page storage location recording function, it is possible to make a transition from a certain page to a page that cannot be directly transited.

As a typical WWW browser which implements the page content recording function and the page storage location recording function, Netscape Communications Corporation (US) Netsc
ape Navigator, Microsoft Corporation Intern
et Explorer is known. Details of the page content recording function and page storage location recording function are described in the above WWW browser specifications (Netscape Communications, N
etscape, Netscape Navigator, U.S. Netscape Commun
Microsoft Corporation, a trademark of Microsoft Corporation.
net Explorer is a trademark of Microsoft Corporation in the United States and other countries.)

[0022]

The problem to be solved by the present invention is that, among the page transitions during execution of a WWW application, the page transition by the page content recording function and the page storage location recording function cannot be suppressed. It is.

FIG. 21 shows an example in which a transaction spanning a plurality of pages cannot be correctly processed. When the page storage location recorded by the page storage location recording function is designated from page X displayed on the WWW browser 2132,
It is possible to transit to page 3 (2133) without going through the WWW server. However, page 3 is page 1, page 2
This is the first valid page via. The product type is determined on page 1 and the data input on page 3 is processed if the product selection and order quantity are not specified on page 2
Inconsistency occurs in processing on the WWW server.

According to the known example 1, the link source and the link destination of the page of interest are extracted and displayed on the screen using a visual figure, so that the relationship between the pages can be recognized without error and an accurate page can be recognized. Although it is possible to create, if the WWW browser uses the page content recording function and the page storage location recording function with the WWW browser, the WWW application can not be executed according to the page transition intended by the designer There is. The problem is also described in the June 1997 (No. 51) Nikkei Open System article pages 213 to 215.

Further, in the conventional WWW application, when setting the user access right level to a plurality of pages in order of page transition, a high user access right level is set to the first page, and There is a problem that the page can be transited even by a user with low access right, and the transition to a specific transition destination page is not restricted.

Further, in the conventional WWW application, when a high user access right level is set for a specific transition destination page, a page transition request from a user who does not satisfy the access right is rejected. If a page transition request to a specific transition destination page is rejected due to lack of access right while transitioning to multiple pages in order, login again with a user ID with high access right Thereafter, it is necessary to perform the page transition again from the beginning of the plurality of pages having the order of the page transition.

An object of the present invention is to solve the above-mentioned problem and to provide a technique capable of preventing a page transition unintended by a designer when a page transition is performed in a sequential page transition. .

Another object of the present invention is to provide a technique capable of collectively managing a plurality of page transition rules.

Another object of the present invention is to provide a technique capable of setting a different access right for each transition destination page having an order of page transition.

Another object of the present invention is to provide a technique capable of changing the access right of the user and continuing the page transition when the access right required for the page transition is insufficient during the sequential page transition. To provide.

[0031]

According to the present invention, in a page transition system for performing a transition between a plurality of pages, a transition destination page which transits from a transition source page is extracted, and transition to the transition destination page is permitted. Creates a page transition rule indicating the transition source page that has been transitioned to the transition destination page if the current page name of the session requested to transition to the transition destination page matches the transition source page in the page transition rule Is performed.

In the page transition definition method of the present invention, a transition destination page which transits from a transition source page is extracted, and the transition source page and the extracted transition destination page are paired and set in a page transition table. A transition source fixed flag indicating whether or not a transition from a page other than the transition source page to the transition destination page is permitted is set in the page transition table.

Next, a transition source page that transits to the transition destination page is extracted from the page transition table, and the transition destination page and the extracted transition source page are paired and set in the transition rule table.

Then, the transition source page of each transition destination page is read from the transition rule table, and a page transition rule indicating a transition source page permitted to transition to the transition destination page is set as a page transition check template statement. Either add to the transition destination page or output the page transition rule of each transition destination page to the transition rule file to manage a plurality of page transition rules collectively.

In the page transition execution method of the present invention, the current page name indicating the currently transitioning page is managed for each session, set in the page management table, and the page transition rule is added to the transition destination page. Read from the check template statement or transition rule file, and if the current page name of the session requested to transition to the transition destination page matches the transition source page in the page transition rule, transition to the transition destination page I do.

As described above, according to the present invention, in a page transition system that transitions between a plurality of pages, it is possible to generate a page transition rule for determining a transition source page that can transition to a specific transition destination page. Thus, even when the WWW browser uses the page content recording function or the page storage location recording function when executing the WWW application, it is possible to prevent the page transition that the designer does not intend.

As described above, according to the page transition system of the present invention, the page transition is performed according to the page transition rule indicating the transition source page permitted to transition to the specific transition destination page. When transitioning a certain page, it is possible to prevent page transition that is not intended by the designer.

[0038]

(Embodiment 1) A page transition rule indicating a transition source page permitted to transition to a specific transition destination page is added to the transition destination file as a page transition check template statement. A page transition system according to the first embodiment for performing transition to a plurality of pages in order using a page transition rule will be described.

FIG. 1 shows an example of a functional configuration of a page transition definition system for realizing the present invention. Frame 101 surrounded by a solid line
Represents a computer that executes the page transition definition system. The computer executes and interprets a program by the CPU 102,
A memory 103 for loading programs, an external storage device 104 for storing programs and data, an input device 105 for inputting data, a display device 106 for displaying calculation results of the CPU 102, and a CPU 102, the memory 103, and the external storage device 10.
4, a bus 107 for connecting data handled by the keyboard 105 and the output device 106.

The external storage device 104 has a page 116 serving as an input / output file of the page transition definition system of this embodiment.
In the directory 115, a page transition check template statement 117 for determining a transition source page that can transition to a transition destination page when executing a WWW application is stored.

The memory 103 is loaded with a program of the page transition definition system of this embodiment. The program includes a page transition definition system control program 108 for controlling the page transition definition system, and a directory 115 specified by the user. From all pages of WWW application
116, a transition destination page that transits from the transition source page is extracted, the transition source page and all extracted transition destination pages are paired and set in the page transition table 113, and the transition state between the pages is determined from the page transition table 113. A page reading program 109 to be displayed on the display 106 using a figure, a page edit for setting a destination page of an arbitrary page as a destination page specified by a user, and setting a page set as a destination page in the page transition table 113 Program 110, page transition table for transition source page to transition to a certain page
A transition rule generation program 111 that sets a pair of the page and all the extracted transition source pages in the transition rule table 114 by extracting the transition page from the transition rule page 114 and a transition source page that can transition to a certain page from the transition rule table 114 The page generation program 112 sets the statement 117 and adds the set page transition check template statement 117 to the transition destination page.

The program for causing the computer 101 to function as a page transition definition device for defining transitions between a plurality of pages is recorded on a recording medium such as a CD-ROM.
It is assumed that after being stored in a storage device such as a magnetic disk, it is loaded into a memory and executed. The medium on which the program is recorded may be a medium other than the CD-ROM.

FIG. 2 shows a schematic flow of the page transition definition system of this embodiment. The process 201 receives an input from the user to the page transition definition system from the keyboard 105. A process 202 analyzes the input content received in the process 201.

A process 203 determines whether the user request is a process for opening a WWW application based on the analysis result of the process 202. If the process is to open the WWW application, process 204
To process 2 if it is not the process to open the WWW application
The process transitions to 07.

In step 204, a directory input from the keyboard 105 by the user is read. The directory is a directory 115 storing pages of the WWW application. The process 205 is performed in the read directory 115
Reads all pages 116 stored in, extracts a set of transition destination pages that can transition from each page for all pages, and pairs the transition source page and all extracted destination pages with a page transition table Set to 113. Processing 2
In step 06, a transition state between pages is graphically displayed on the display 106 from the page transition table 113.

The process 207 determines whether the user request is a page property editing process based on the analysis result of the process 202. In the case of the page property editing process, the process is shifted to a process 208, and in the case of not being the page property editing process, the process is shifted to a process 209. The process 208 sets the destination page of the arbitrary page as the destination page specified by the user, and sets the page set as the destination page in the page transition table 113.

In step 209, it is determined from the analysis result of step 202 whether the user's request is a page generation process. If it is a page generation process, go to process 210; if it is not a page generation process, process 2
The process transitions to 11. The process 210 extracts from the page transition table 113 a set of transition source pages that can transition to a certain page, and sets the transition destination page and all extracted transition source pages as a pair in the transition rule table 114. Processing 211 is
A transition source page that can transition to a certain page is set in the page transition check template statement 117 from the transition rule table 114, and the set page transition check template statement 117 is added to the transition destination page.

In the process 212, it is determined from the analysis result of the process 202 whether the user request is a termination process. In the case of end processing, this flow is ended and the page transition definition system is ended. If it is not the end process, the process is shifted to the process 201.

FIG. 3 shows an example of the screen operation of the process 204 for reading the directory 115 input from the keyboard 105 by the user. A window 301 is a page transition definition editor of the page transition definition system of the present embodiment. When a command 303 to be opened from the file menu 302 is selected with the mouse 304, a dialog 305 for specifying the directory 115 is displayed. When the directory 115 storing the WWW application is specified in the text box 306 and the button 307 is selected with the mouse 308, the page of the WWW application is read from the specified directory 115.

Next, all pages 116 stored in the read directory 115 are read, and for all pages,
A process 205 of extracting a set of transition destination pages that can transition from each page and setting the set of the transition source page and the extracted transition destination page in the page transition table 113
Will be described with reference to FIG.

The process 401 initializes the control variable i with 0.
The value of the control variable i represents the number of pages. The process 402 adds 1 to the control variable i. The process 403 reads the i-th page. The process 404 adds a record for setting the transition destination page of the i-th page to the page transition table 601 in FIG. processing
Reference numeral 405 sets the page name 602 of the added record to the file name of the i-th page, 0 to the transition source fixed flag 603, and NULL to the transition destination page list pointer 604.

Step 406 initializes the control variable j with 0.
The value of the control variable j represents the number of lines of the statement described in the i-th page read in the process 403. Process 407
Adds 1 to the control variable j. The process 408 is performed on the i-th page
Extract the j-th line. A process 409 determines whether the tag described in the fetched line is a file link. If the tag is a file link, the process proceeds to step 410. If the tag is not a file link tag, the process proceeds to step 413.

The process 410 extracts the file name of the link destination. The process 411 determines whether the file name extracted in the process 410 is already set in the transition destination page list 605 of the record of the page transition table 601 added in the process 404. If the file name has been set, the process proceeds to step 413; otherwise, the process proceeds to step 412. Process 412
The file name extracted in the process 410 is set in the transition destination page list 605 of the record of the page transition table 601 added in the process 404. The process 413 determines whether the value of the control variable j is the last line of the i-th page. Process 4 if the value of control variable j is the last line
If it is not the last line, the process proceeds to step 407.

In the process 414, the value of the control variable i is
It is determined whether it is the last page of the WWW application stored in 115. Process 415 if the value of control variable i is the last page
If it is not the last page, the process proceeds to step 402. Processing 4
15 displays the page transition of the WWW application from the value set in the page transition table 601.

Line 508 is a tag indicating the start of the description of the main contents of the HTML file. Line 509 is a tag for linking with another HTML file. Line 510 is a tag indicating the end of the description of the main contents of the HTML file. Line 511 is a tag indicating the end of the HTML file.

FIG. 6 shows the record format of the page transition table 113. The record of the page transition table 601 includes a page name 602, a transition source fixed flag 603, and a transition destination page list pointer 604.

In the page file name 602, the file name of the page is set. The transition source fixed flag 603 is set to 0 or 1. If 0 is set, it means that the transition to the page set in the page name 602 is permitted even from a page other than the transition source page. Page name 602 when 1 is set
This means that the user cannot permit the transition to the page set in the page other than the transition source page explicitly specified by the user in the page transition definition editor. Transition destination page list pointer 60
In 4, a pointer to the transition destination page list 605 is set.

Next, an example in which specific data is set in the page transition table 113 will be described. In the page transition table 113, data is set in four records. The page name 609 of the record 608 is the file name of the page “page1.html”, the transition source fixed flag 610 is “0” that allows page transition even from a page other than the transition source page, and the transition destination page list pointer 611 is Transition destination page list 6
Pointer to 12 is set. Transition destination page list
In 612, file names of two transition destination pages are set. “Page2.html” is set for the transition destination page name 613, and “page4.html” is set for the transition destination page name 614.

FIG. 7 shows the WWW displayed on the display 106.
An example of page transition of an application has been described. A window 701 is a page transition definition editor of the page transition definition system of the present embodiment. A window 701 displays the page transition state of the WWW application. The page icon 702 represents one page in the WWW application. An arrow 703 represents a page transition. Arrow 703
Indicates that a link for transitioning from page 704 to page 702 is set.

By clicking the page icon 801 with the right mouse button, a page property menu 802 is displayed.
Is displayed. The page property menu 802 includes a page name text 803, a transition source page name list 804, and a transition fixed setting combo box 805.

The page name text 803 displays the file name of the page. The transition source page name list 804 displays the file names of pages that can transition to the target page. The transition fixed setting combo box 805 displays whether or not to limit the pages that can be transitioned to the target page to only the pages displayed in the transition source page list 804.
The setting can be made by clicking the transition fixed setting combo box 805 with the mouse 806 and selecting and specifying “Yes” or “No”.

Next, FIG. 9 shows the screen operation flow of FIG. A process 901 determines a page transition fixing operation.
If “Yes” is selected, the process proceeds to step 902; if “No” is selected, the process proceeds to step 903. Process 902 includes:
Set the value of the transition source fixed flag 603 of the page transition table 601 to 1
And the flow ends. The process 903 sets the value of the transition source fixed flag 603 of the page transition table 601 to 0, and ends this flow.

Next, for each page in the WWW application, a transition source page that can transition to each page is extracted from the page transition table 113, and the transition destination page and all extracted transition source pages are paired. The process 210 set in the transition rule table 114 will be described with reference to FIG.

A process 1001 initializes a control variable i with 0.
The value of the control variable i represents the number of records in the page transition table 601. The process 1002 adds 1 to the control variable i. The process 1003 determines the value of the transition source fixed flag 603 of the i record of the page transition table 601. If the value is 0, process 1013
If it is 1, the process proceeds to the process 1004.

The process 1004 initializes the control variable j with 0.
The value of the control variable j represents the number of records in the page transition table 601. The process 1005 adds 1 to the control variable j. The process 1006 compares the values of the control variables i and j. If the values of i and j are the same, the process proceeds to step 1005;

In the process 1007, the value of the page name 602 of the i-th record of the page transition table 601 is
It is determined whether or not it is set in the transition destination page list 605 of the j-th record. If it has been set, the process proceeds to step 1008; otherwise, the process proceeds to step 1005.

The process 1008 determines whether the value of the page name 602 of the i-th record in the page transition table 601 is set in the transition destination page name 1102 of the transition rule table 1101 in FIG. If it is set, the process proceeds to step 1011; otherwise, the process proceeds to step 1009. The transition rule table 1101
Is a table in which a transition destination page is associated with a transition source page that can transition to the transition destination page.

The process 1009 adds a new record for setting the page name 602 of the i-th record of the page transition table 601 to the transition rule table 1101. The process 1010 sets the page name 602 of the i-th record of the page transition table 601 as the transition destination page name 1102 of the record of the newly added transition rule table 1101. The process 1011 is performed in the transition rule table 1
Page transition table 601 in 101 transition source page list 1104
The page name 602 of the j-th record is set.

The process 1012 determines whether the value of the control variable j is the last record. If the value of the control variable j is the last record, the process proceeds to step 1013; otherwise, the process proceeds to step 1005. The process 1013 determines whether the value of the control variable i is the last record. If the value of the control variable i is the last record, the flow is terminated.

FIG. 11 shows the record format of the transition rule table 114. The record 1101 of the transition rule table 114 includes a transition destination page name 1102 and a transition source page list pointer 1103. In the transition destination page name 1102, a file name of the transition destination page is set. In the transition source page list pointer 1103, a pointer to the transition source page list 1104 is set.

Next, an example in which specific data is set in the transition rule table 114 will be described. In the transition rule table 114, data is set in four records. The file name “page1.html” of the transition destination page is set in the transition destination page name 1108 of the record 1107, and the pointer to the transition source page list 1110 is set in the transition source page list pointer 1109. In the transition source page list 1110, a transition source page name 1111 is set. Source page name 11
11 has “page3.html” set.

Next, for all the pages whose transition sources are limited from the transition rule table 114, the transition source pages that can transition to that page are set in the page transition check template statement 117, and the set page transition check template The process 211 for adding the statement 117 to the transition destination page will be described with reference to FIG.

The program for causing the computer 101 to function as a page transition definition device for defining transitions between a plurality of pages is recorded on a recording medium such as a CD-ROM.
It is assumed that after being stored in a storage device such as a magnetic disk, it is loaded into a memory and executed. The medium on which the program is recorded may be a medium other than the CD-ROM.

FIG. 23 shows a schematic flow of the page transition definition system. The process 201 receives an input from the user to the page transition definition system from the keyboard 105. A process 202 analyzes the input content received in the process 201.

In the process 203, it is determined from the analysis result of the process 202 whether the user's request is a process for opening the WWW application. If the process is to open the WWW application, process 204
To process 2 if it is not the process to open the WWW application
The process transitions to 07.

In step 204, the directory input from the keyboard 105 by the user is read. The directory is a directory 115 storing pages of the WWW application. A process 205 reads all the pages 116 stored in the read directory 115, extracts a set of transition destination pages that can transition from each page for all pages, and defines a transition source page and all extracted transition destinations. The pages are set in the page transition table 113 in pairs.
A process 206 reads the transition state between pages from the page transition table 113 and displays the transition state on the display 106 as a graphic.

In the process 207, it is determined from the analysis result of the process 202 whether the user request is a page property editing process. In the case of the page property editing process, the process is shifted to a process 208, and in the case of not being the page property editing process, the process is shifted to a process 209. The process 208 sets the transition destination of the arbitrary page as the transition destination page specified by the user, and sets the page set as the transition destination page in the page transition table 113.

In the process 209, it is determined from the analysis result of the process 202 whether the user request is a page transition rule generation process. In the case of the page transition rule generation process, the process is shifted to the process 2301; otherwise, the process is shifted to the process 212. A process 2301 displays a dialog window for selecting whether to output the page transition rule to a template or a file.

FIG. 24 shows the dialog window. Dialog window 2401 is a radio button 2402, radio button 2403 to select the output destination of the page transition rule to be a template or a file, and a file name to input the output destination file name when the output destination of the page transition rule is selected to a file Input field 2404, dialog window 24
It comprises an OK button 2405 and a cancel button 2406 for confirming the process of 01.

To output a page transition rule to a template, check the radio button 2402. To output the page transition rule to a file, check the radio button 2403 and enter the file name of the page transition rule in the file name input field 2404.

The process 2302 judges the result of the process of the dialog window 2401. If the OK button 2405 is selected, the process proceeds to step 210, and if the cancel button 2406 is pressed, the process proceeds to step 206.

The process 210 extracts from the page transition table 113 a set of transition source pages that can transition to a certain page,
The transition destination page and all extracted transition source pages are paired and set in the transition rule table 114.

The process 2303 determines the output type of the page transition rule. If the radio button 2402 has a check, the process proceeds to a process 211. If the radio button 2403 has a check, the process proceeds to a process 2304.

The process 211 stores a page transition rule indicating a transition source page capable of transitioning to a certain page in a transition rule table.
The page transition check template statement 117 is set from 114, and the set page transition check template statement 117 is added to the transition destination page. In step 2304, the page transition rule is output from the transition rule table 114 to the transition rule file 2202.

In the process 212, it is determined from the analysis result of the process 202 whether the user's request is a termination process. In the case of the end processing, the present flow ends, and the page transition definition system ends.
If it is not the end process, the process is shifted to the process 201.

FIG. 25 shows a transition rule file according to this embodiment.
FIG. 220 is a diagram illustrating an example of a 2202. The transition rule file format 2501 of the transition rule file 2202 includes records of a plurality of record formats 2502. Record format 2502 consists of transition destination page name 2503 and concatenated character 2504
And a rule character string 2505.

In the transition destination page name 2503, a transition destination page name is set. In the rule character string 2505, a page name of a transition source that can transition to the transition destination page is set. If there are a plurality of transition source pages, link the transition source page names with commas ','. The connection character 2504 is a delimiter colon “:” that connects the transition destination page name 2503 and the rule character string 2505.

An example of the transition rule file 2202 is shown in the transition rule file 2506. Next, the transition rule table
A detailed flow of generating the transition rule file 2506 from 1101 will be described with reference to FIG.

FIG. 26 shows a transition rule file according to this embodiment.
35 is a flowchart illustrating a processing procedure of processing for generating 2506. The process 2601 sets the character string input in the file name input field 2404 as the file name, and
Generate 06. The process 2602 initializes the control variable i with 0. The value of the control variable i represents the number of records in the transition rule table 1101. The process 2603 adds 1 to the control variable i.

In the process 2604, a new record 2507 is generated in the transition rule file 2506. The process 2605 obtains the page name of the transition destination page name 1102 of the i-th record of the transition rule table 1101 and records the record 25 as the transition destination page name 2503.
Output to 07. The process 2606 outputs a concatenated character 2504 ′: ′ of the transition destination page name 2503 and the rule character string 2505 to the record 2507.

The process 2607 is performed in accordance with i in the transition rule table 1101.
A rule character string is created by linking the transition source page names set in the transition source page list 1104 of the record with commas ','. The process 2608 outputs the rule character string 2505 generated in the process 2607 to the record 2507. The process 2609 outputs a line feed code.

The processing 2610 makes a final record determination. i
If the record is not the last record of the transition rule table 1101, the processing transits to Step 2603. If the i-th record is the last record of the transition rule table 1101, the flow ends.

As described above, in the present embodiment, it is possible to embed the page transition rule of the WWW application composed of a plurality of pages for each page, and to collectively manage the rules with one file.

A description will now be given of an embodiment of a page transition definition system capable of generating a transition rule file 2202 in which a user access right level is set for each page.
In the present embodiment, even if a valid page transition is generated in the transition rule file 2202, the page transition is restricted according to the access right level of the user who wants to transition the page.

FIG. 27 shows the record format of the page transition table 113 in which the level of the user access right is set for each page. Page transition table record
Reference numeral 2701 denotes a page name 2702, a user access right level 2703, a transition source fixed flag 2704, and a transition destination page list pointer 27.
Consists of 05.

In the page name 2702, a file name of the page is set. In the user access right level 2703, a level indicating a user access right that can transition to the page set to the page name 2702 is set. The page can be transited only by a user having a user access right equal to or greater than the level set in the user access right level 2703.

In the transition source fixed flag 2704, 0 or 1 is set. If 0 is set, it means that the transition of the page set in the page name 2702 is permitted even from a page other than the transition source page, and the numerical value set in the user access right level 2703 is invalid. If 1 is set, page name 2702
This means that the user cannot permit the transition to the page set in the page other than the transition source page explicitly specified by the user in the page transition definition editor. Transition destination page list pointer 27
In 05, a pointer to the transition destination page list 2707 is set.

Next, FIG. 28 shows a flow for setting the user access right level for each page in the page transition table 2713.
It was shown to. First, the process 2801 initializes the control variable i with 0. The value of the control variable i is the number of pages of the WWW application read in the process 204. The process 2802 adds 1 to the control variable i. A process 2803 reads the i-th page of the page of the WWW application read in the process 204.

The process 2804 adds a new record 2708 to the page transition table 2713. The process 2805 sets the file name of the i-th page in the page name 2709 of the record 2708 added in the process 2804, sets the transition source fixed flag 2711 to 0, and sets the transition destination page list pointer 2712 to NULL. Processing 2806 is processing 2804
Access level 2710 for record 2708 added in
Set to 0.

A process 2807 initializes the control variable j with 0.
The value of the control variable j indicates the number of lines of the statement described in the i-th page read in the processing 2803. Process 28
08 adds 1 to the control variable j. The process 2809 extracts the j-th line of the i-th page.

The process 2810 determines whether or not the tag described in the fetched line is a file link. If the tag is a file link, the process proceeds to step 2811; otherwise, the process proceeds to step 2814.

In step 2811, the file name of the link destination is extracted. Process 2812 is a transition destination page list pointer 2712 of the record of the page transition table 2713 added in process 2804.
It is determined whether or not the file name extracted in step 2811 has already been set in the transition destination page list 2714 pointed by.
If the file name has been set, the process proceeds to step 2814; otherwise, the process proceeds to step 2813.

In step 2813, the file name extracted in step 2811 is added to the list 2714 of the transition destination page of the i-th record added in step 2804. A process 2814 determines whether the value of the control variable j is the last line of the i-th page. If the value of the control variable j is the last line, the process shifts to step 2815; if not, the process shifts to step 2808.

A process 2815 determines whether the value of the control variable i is the last page of the WWW application stored in the directory 115. If the value of control variable i is the last page, process 281
If it is not the last page, the process proceeds to the process 2802. A process 2816 displays the page transition of the WWW application from the value set in the page transition table 2713, and ends this flow.

Next, an example of a screen operation for setting a user access right level for an arbitrary page displayed on the display 106 will be described with reference to FIG.

The page property menu 2901 is obtained by adding a user access right level setting menu to the page property menu 802 in FIG. By clicking the page icon 801 with the right mouse button, a page property menu 2901 is displayed.

The page property menu 2901 includes a page name text 803, a transition source page name list 804, a user access right level setting list 2902, and a transition fixed setting combo box 805.

The page name text 803 displays the file name of the page. The transition source page name list 804 displays the file names of pages that can transition to the target page. The user access right level setting list 2902 displays user access right levels. Click the user access right level setting list 2902 with the mouse pointer 2903 to set the user access right level.
04 can be displayed and set by selecting and specifying an arbitrary level in the level list 2904.

[0157] In the transition fixed setting combo box 805, a page that can be transitioned to the target page is a transition source page list.
Whether or not to limit only to the page displayed in 804 is displayed. In the screen operation for setting the user access right level, the transition fixing is set to “Yes” to make the user access right level valid.

Next, the screen operation flow of FIG. 29 is shown in FIG. The process 3001 determines the operation of the user access right level setting list 2902. If the user access right level is to be changed, the process proceeds to step 3002; otherwise, the flow ends.

The process 3002 selects an arbitrary level from the level list 2904. The process 3003 sets the level selected in the process 3002 to the page transition table record 27 of any page.
Set the user access right level of 2703 to 01. Process 3004
Sets the display of the user access right level setting list 2902 of the page property menu 2901 to the level selected in the process 3002, and ends this flow.

FIG. 31 shows a record format of the transition rule table 114 in which the user access right level is set for each page. Transition rule table record 3101
Is the transition destination page name 3102 and the user access right level 31
03 and a transition source page list pointer 3104.

In the transition destination page name 3102, the file name of the transition destination page is set. In the user access right level 3103, a user access right level of the transition destination is set. The transition source page list pointer 3104 has a transition source page list
A pointer to 3105 is set.

Next, a flow for setting the user access right level for each page in the transition rule table 3107 will be described with reference to FIG.
This will be described with reference to FIG. First, the process 3201 initializes the control variable i with 0. The value of the control variable i is set in the page transition table 2713.
Indicates the number of records. Process 3202 is performed by setting 1 to the control variable i.
Is added. The process 3203 is executed in the page transition table 2713
Transition source fixed flag 2711 of record 2708 of the i-th record of
Is determined. If the transition source fixed flag 2711 is “1”, the process is shifted to the process 3204, and if “0”, the process is shifted to the process 3214.

In step 3204, the control variable j is initialized to 0.
The value of the control variable j indicates the number of records in the page transition table 2713 which is to be compared with the records of the page transition table 2713 indicated by the value of the control variable i. Process 3205 is
1 is added to the control variable j.

The process 3206 compares the values of the control variable i and the control variable j. If the value of the control variable i is equal to the value of the control variable j, the process proceeds to the process 3205; otherwise, the process proceeds to the process 3207.

The processing 3207 is performed by using i in the page transition table 2713.
It is determined whether the page name 2709 of the record 2708 of the record is set in the transition destination page list 2716 of the transition destination page list pointer 2712 of the record 2715 of the j-th record of the page transition table 2713. Process 3208 if set
If not set, the process proceeds to the process 3205.

The process 3208 is performed by setting i in the page transition table 2713 to i.
It is determined whether the page name 2709 of the record 2708 of the record is set as the transition destination page name 3109 of the transition rule table 3107. If it has been set, the process proceeds to step 3212; otherwise, the process proceeds to step 3209.

The process 3209 adds a new transition rule table record 3108 to the transition rule table 3107. Process 32
10 sets the page name 2709 of the record 2708 of the i-th record of the page transition table 2713 as the transition destination page name 3109 of the added transition rule table record 3108.

The process 3211 sets the user access right level 2710 of the record 2708 of the i-th record of the page transition table 2713 to the user access right level 3110 of the added transition rule table record 3108.

The processing 3212 is a transition rule table record
The page name 2709 of the record 2715 of the j-th record of the page transition table 2713 is set in the transition source page list 3112 of the transition source page list pointer 3111 of 3108. Process 3213
Determines whether the value of the control variable i is the last record. If it is the last record, the process proceeds to step 3217, and if it is not the last record, the process proceeds to step 3205.

The process 3214 which has shifted from the process 3203 adds a new transition rule table record 3108 to the transition rule table 3107. Processing 3215 is performed by adding the transition destination page name 3109 of the added transition rule table record 3108 to the page name 2 of the i-th record 2708 of the page transition table 2713.
Set 709.

A process 3216 sets a symbol “*” that allows a transition from an arbitrary page to the transition source page name 3113 of the transition source page list 3112 of the added transition rule table record 3108, and shifts the process to the process 3217. I do.

The process 3217 determines whether or not the value of the control variable i is the last record. If it is not the last record, the process is shifted to the process 3202. If it is the last record, the flow ends. The transition rule table 3107 in FIG. 31 shows an example of the result of the flow.

FIG. 33 shows an example of a file format of the transition rule file 2202 in which the user access right level is set for each page. The transition rule file format 3301 includes records of a plurality of record formats 3302. The record format 3302 includes a page name character string 3303, a rule character string 3304, and a user access right level 3305.

As described above, in the present embodiment, it is possible to prevent unintended page transition by the designer even when the WWW browser uses the page content recording function or the page storage location recording function when executing the WWW application. Become
Page transition can be controlled at each user access right level.

FIG. 46 is a flowchart showing the procedure of a page generation process 4403 for creating a page to be transmitted to the WWW browser according to the present embodiment. The process 4601 is executed by executing a page 1515 corresponding to the temporary variable movePage from the directory 1514.
Read. The process 4602 initializes the control variable i with 0.
The value of the control variable i indicates the number of lines of the page read in the process 4601. The process 4603 adds 1 to the value of the control variable i.

At step 4604, the i-th row of the page read at step 4601 is extracted. A process 4605 determines whether the fetched line is a link tag to a page. If the tag is a link tag to a page, the process proceeds to step 4606; otherwise, the process proceeds to step 4607.

[0239] In step 4606, the format of the link URL 3902 to the page of the link tag to the page is set to the page request URL 39
Change to 03 format. A process 4607 stores the fetched line in a buffer for transmission to the WWW browser, and generates a page. A process 4608 determines whether the i-th line is the last line of the page. If it is not the last line, the process proceeds to the process 4603. In the case of the last line, this flow ends.

As described above, in the present embodiment, it is possible to restrict the page transition by the difference in the user access right level, and to prevent the page transition other than the authorized user and the page transition of the unauthorized user. Can be.

Next, an example of a description example of a page to which a unique tag for changing the display content of the page according to the user access right level is added will be described.

FIG. 47 is a diagram showing an example of HTML for changing the display content of a page according to the user access right level according to the present embodiment. The access level tag 4701 represents a description example of a tag for changing the display content of a page according to the user access right level of the user who has requested the transition to the transition destination page.

The n of the access level tag 4701 is an argument of the tag. The value of argument n is the access level start tag 4702
And the lowest user access right level at which a tag group surrounded by the access level end tag 4703 can be displayed. The tag group has a user access right level of the user who has requested the transition to the transition destination page. It will be displayed only in the above cases.

On page 4704, page link tag 4705 sandwiched between access level 1 tags that can be displayed only when the user access right level is 1 or higher, and display only when the user access right level is 2 or higher An example of a page link tag 4706 sandwiched between access level 2 tags is shown.

As described above, in this embodiment, it is possible to define a description of a page whose display content is to be changed according to the user access right level of the user who has requested the transition to the transition destination page.

FIG. 48 is a flow chart showing a processing procedure of processing for changing the display contents of a page according to the user access right level according to the present embodiment. This flow represents a detailed flow in which a process of changing the display content of a page according to the user access right level is added to the flow 4600 of the process 4403.

As shown in FIG. 48, the process 4801 reads a page 1515 corresponding to the temporary variable movePage from the directory 1514. The process 4802 sets 0 to the temporary variable findLevel. The value of the temporary variable findLevel holds the value of the argument of the access level start tag 4702.

The process 4803 sets the value of the temporary variable makeHTML flag to TRUE. If the value of the temporary variable makeHTML is "TRUE", a code is generated and the currently processed code is displayed.If "FALSE", the code is not generated and the currently processed code cannot be displayed. State.

The process 4804 initializes the control variable i with 0.
The value of the control variable i indicates the number of lines of the page read in the process 4801. The process 4805 adds 1 to the value of the control variable i. A process 4806 extracts the i-th line of the page read in the process 4801. The process 4807 determines the code on the i-th line extracted in the process 4806. If the i-th line is an access level tag code, the process proceeds to step 4813; otherwise, the process proceeds to step 4808.

At step 4808, the value of the temporary variable makeHTML is determined. When the temporary variable makeHTML flag is TRUE, the process proceeds to a process 4809 for generating a code. When the temporary variable makeHTML flag is FALSE, the process is shifted to a process 4812 without generating a code.

The process 4809 determines whether the fetched line is a link tag to a page. If it is a link tag to a page, go to step 4811. If it is not a link tag to a page, go to step 4811.
Move the processing to 4810. The process 4811 changes the format of the link URL 3902 to the page of the link tag to the page to the format of the page request URL 3903. Process 4810 stores the fetched line in a buffer for transmission to the WWW browser,
Generate a page.

The process 4813 sets the value set in the argument of the access level tag code to the temporary variable showLevel. A process 4814 determines whether the access level tag code extracted in the process 4806 is an access level start tag 4702 or an access level end tag 4703. In the case of the access level start tag 4702, the processing proceeds to processing 4819, and the access level end tag 47
In the case of 03, the process is shifted to the process 4815.

In the process 4819, it is determined whether or not the temporary variable findLevel is 0. If the temporary variable findLevel is 0, process to determine whether the code enclosed by the access level tag can be displayed
Move the processing to 4820. If the temporary variable findLevel is other than 0, the code cannot be displayed, and the process shifts to the process 4812.

In the process 4820, a temporary variable userLeve is obtained in the process 4513.
Compare the value set in l with the value of the temporary variable showLevel. When the value of the temporary variable userLevel is smaller than the value of the temporary variable showLevel, the process is transited to the process 4821 to make it impossible to display the code surrounded by the access level tag. When the value of the temporary variable userLevel is equal to or greater than the value of the temporary variable showLevel, the process is transited to the process 4812 because the display is possible.

The process 4821 sets the temporary variable makeHTML flag to FA
Set to LSE. The process 4822 sets the temporary variable showLevel to the temporary variable findLevel.

In the process 4815, it is determined whether or not the value of the temporary variable findLevel is 0. If the value of the temporary variable findLevel is 0, process 48
To 08, processing 4816 when the value of the temporary variable findLevel is other than 0
The process is shifted to

The process 4816 compares the value of the temporary variable findLevel with the value of the temporary variable showLevel. Temporary variable findLevel
If the value of is not equal to the value of the temporary variable showLevel, the code cannot be displayed, and the process shifts to the process 4812. When the value of the temporary variable findLevel is equal to the value of the temporary variable showLevel, it is determined to be the access level end tag 4703 that is paired with the access level start tag 4702 which is not displayed, and the process proceeds to the process 4817 for enabling display. Let it. Processing 4817 is
The value of the temporary variable findLevel is set to 0, and operation 4818 sets the value of the temporary variable makeHTML flag to TRUE.

The process 4812 judges whether the i-th line is the last line of the page. If it is not the last line, the process shifts to step 4805, and if it is the last line, this flow ends.

As described above, in the present embodiment, even if the page transitions to the same page, the display content of the page can be changed depending on the difference in the user access right level.

As described above, according to the page transition system of this embodiment, the page transition is performed according to the page transition rule indicating the transition source page permitted to transition to the specific transition destination page. It is possible to prevent a page transition unintended by the designer when performing a page transition with a possibility.

According to the page transition system of this embodiment, the page transition rules of each transition destination page are output to the transition rule file, so that a plurality of page transition rules can be managed collectively.

According to the page transition system of the present embodiment, the user access right level indicating the access right that can transition to the transition destination page is set in the page transition rule, and the page transition is performed according to the user's access right. It is possible to set a different access right for each transition destination page having an order of page transition.

Further, according to the page transition system of this embodiment, a login page is created when the access right to the transition destination page is not sufficient. Is insufficient, it is possible to change the user's access right and continue the page transition.

The memory 4909, the external storage device 4907, the LAN adapter 4906, the keyboard 4905, and the display 4908 are connected by a bus 4910 for mutually transmitting and receiving data.

The memory 4909 is loaded with the program of the page transition execution system of this embodiment. The page transition execution system of the present embodiment transmits a page acquisition request to the server computer 4901, receives a page corresponding to the acquisition request, a WWW browser control program 4911, and a session management for establishing a connection with the server computer 4901. Table 1527, a page transition control program 4912 that determines whether a page received from the server computer 4901 is a page to be subjected to page transition control, and displays a page received from the server computer 4901 based on the determination result of the page transition control program 4912. Page display program 4913, based on the result determined by the page transition control program 4912, the page content displayed by the display program 4913 is temporarily stored in an external storage device.
A page location recording program 4914 is stored in the external storage device 4907 and recorded in the page location recording table 4916.

The program for causing the client computer 4903 to function as a page transition execution device for executing transition between a plurality of pages is recorded on a recording medium such as a CD-ROM and stored in a storage device such as a magnetic disk. Later, it will be loaded into the memory and executed. The medium on which the program is recorded may be a medium other than the CD-ROM.

FIG. 50 shows a client computer according to the present embodiment.
It is a flowchart which shows the processing procedure of 4903. Processing 5001
Determines the state of the WWW browser program. If the state of the WWW browser program is determined to be an input operation by the user, the process proceeds to step 5002, and if a response result returned from the server computer 4901 is received, the process proceeds to step 5011.

The process 5002 determines whether or not the user's input operation is a click on the “return” button for returning the page to the immediately preceding page. If the input operation by the user is a click on the “return” button, the process proceeds to step 5017.
If it is not the click of the “return” button, the processing transits to Step 5003.

The process 5003 determines whether or not the user's input operation is a click on the “forward” button, which is an operation for advancing a page to the next page. If the input operation by the user is a click on the “forward” button, the process proceeds to step 5017.
If it is not a click on the “forward” button, the process transits to processing 5004.

The process 5004 determines whether or not the input operation by the user is a click on the “reload” button for redrawing the current page. If the input operation by the user is a click on the “reload” button, the process proceeds to step 5017. If the input operation is not a click on the “reload” button, the process proceeds to step 5005.

In the process 5005, when the input operation by the user is a URL
It is determined whether the input is in the "URL" text input area that directly specifies the URL. If the input operation by the user is a URL input to the “URL” text input area, the process proceeds to step 5008. If the input operation is not an input to the “URL” text input area, the process proceeds to step 5006.

The process 5006 determines whether or not the input operation by the user is a click on the “anchor” set on the page. If the input operation by the user is a click on the "anchor" set on the page, go to step 5008; otherwise, a process 5007.

In the process 5007, when the input operation by the user is WWW
It is determined whether the operation is a browser program end operation. If the input operation by the user is the end operation of the WWW browser program, this flow ends and the data is loaded into the memory 4909.
Remove the WWW browser program. If the operation is not the end operation of the WWW browser program, the processing transits to Step 5001.

The process 5008 determines whether or not the session ID is set in the session management table 1527 of the WWW browser program. The session ID is an identifier for uniquely determining a connection with the server computer 4901 that transmits a page request from the WWW browser program. The session ID is obtained from the WWW browser program to the server computer 4.
When the first page request command is transmitted to the 901, the server computer 4901 generates the page request command and, as a result of the page request command,
It is returned to the browser program in pair with the response page.

The session ID returned to the WWW browser program is set in the session management table 1527 in a pair with the URL of the requested page. Processing 5009 when session ID is set in session management table 1527
If not set in the session management table 1527, the process transits to Step 5010.

The process 5009 transmits a page request command with session ID to the server computer 4901. The command includes a URL of a page requested from the server computer 4901 and a session ID.
It is. Processing 5010 is performed by setting the session ID to server computer 4901.
None Send a page request command. The command is only the URL of the page requested from the server computer 4901.

The process 5011 judges whether or not the session ID returned from the server computer 4901 is set in the session management table 1527. Process 5013 when the session ID is set in the session management table 1527
If the session ID is not set in the session management table 1527, the process transits to Step 5012. Process 5012 is
The session ID returned from the server computer 4901 is set in the session management table 1527 in pair with the URL of the page requested to the server computer 4901.

The process 5013 determines whether or not the page returned from the server computer 4901 is a page with a page transition check template statement. An example of a page with a page transition check template statement is shown in FIG. Inside the solid line frame 1401 is a page with a page transition check template statement. The page with the page transition check template statement has the page transition check template statement shown in the dotted frame 1402 described in the first line.

If a page transition check template statement is described at the beginning of the page returned from the server computer 4901, the process proceeds to step 5016 where the server computer 49
If the page transition check template statement is not described at the top of the page returned from 01, the flow shifts to step 5014.

In the process 5014, the page returned from the server computer 4901 is stored in a directory in the external storage device 4907 specified in advance by the WWW browser program. Process 5015
Records the location of the page stored in the external storage device 4907 in the page location record table 4916. Details of the page location record table 4916 will be described with reference to FIG. 51, and details of the process 5015 will be described with reference to FIG.

[0283] In the process 5016, the page returned from the server computer 4901 is displayed on the display 4908. Process 5017
Reads the page from the location of the page recorded in the page location record table 4916 in the process 5015, and displays the read page on the display 4908. Details of the process 5016 will be described with reference to FIG.

FIG. 51 shows the format of the page location record table 4916 by a dotted frame 5101. The page location record table 4916 has a record page number 5102 holding the total number of pages stored in the directory in the external storage device 4907 previously specified by the WWW browser program, and a record page location path list 5103 holding the directory path of the stored page.
Consists of

A page location record table 4916 is set in a dotted frame 5104.
An example in which specific data is recorded is shown. In the number of recorded pages 5105, “3” which is the total number of pages stored in a directory in the external storage device 4907 previously specified by the WWW browser program is recorded. Three directory paths in the external storage device 4907 storing the recorded pages are recorded in a dotted frame 5106. A dotted frame 5107 indicates the external storage device 4907 specified in advance by the WWW browser program.
The dotted line frame 5108 shows the name of the page.

FIG. 52 shows the detailed flow of the process 5015 for recording the location of the page stored in the external storage device 4907 in the page location record table 4916. Processing 5201 adds 1 to the value of the number of recorded pages 5102 in the page content recording table 5101. Process 5202 adds one page directory path area for recording the directory path of the page stored in the external storage device 4907 to the recording page location path list 5103 of the page content recording table 5101. Process 5203
Records the file path of the page stored in the external storage device 4907 in the added recording page directory path area.

FIG. 53 shows the detailed flow of processing 5017 for reading a page from the location of the page recorded in the page location record table 4916 and displaying the read page on the display 4908. The processing 5301 subtracts 1 from the value of the number of recorded pages 5102 in the page content recording table 4901. A process 5302 reads a page from the recording page directory path recorded in the last line of the recording page location path list 5103 of the page content recording table 4901. The process 5303 displays the read page on the display 4908. Process 5304
Deletes the last line of the recording page location path list 5103 of the page content recording table 4901.

As described above, in the present embodiment, it is possible to prevent a page transition unintended by the designer even when the page content recording function is used in the WWW browser when executing the WWW application.
