DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an HTML (Hyp
pages written in a markup language such as ertext Markup Language), for example, WWW
The present invention relates to a page display control device, a page display control method, and a page display control program recording medium for controlling display of a Web page that provides information in a (World Wide Web) system.

[0002]

2. Description of the Related Art The same URL (Uniform Resource) is set according to a user who accesses a WWW server.
Locator), there is a demand to change the display content of the Web page provided. Conventionally, in order to change the contents of a Web page displayed for each user who has accessed a WWW server, a CGI (Common Gate) has been required.
A special program called a "way interface" or a script file corresponding to the program is constructed on a WWW server to dynamically create an HTML source.

[0003]

However, the development and creation of CGI programs and script files requires the acquisition of advanced expertise in programming and development languages, and not everyone can easily do it. ,
Even after development and creation, each time the layout of a Web page is changed, the CG is adjusted according to the changed page.
Since it is necessary to re-create the I program or the like and check the operation, there is a problem that labor and time cost are required.

[0004] An object of the present invention is to divide an HTML source constituting a Web page into a plurality of parts, display an access right for each part, and display contents according to a user, for example, in displaying a Web page. It is an object of the present invention to provide a device or the like that can easily construct a Web page that changes.

[0005]

In order to solve the above problems, the present invention has means as shown in FIG. FIG.
2 shows a block configuration example of a Web page display control device for a Web page described in TML.

[0006] The divided file storage means 1 is a means for storing an HTML source file divided for each part having different access authority. User information storage means 2
Is the user ID, password,
This is a means for storing user information such as belonging group. The configuration information definition storage unit 3 uses any one of the divided HTML source files to
This is a means for storing definition information on whether to synthesize the L source.

[0007] The access right setting processing means 4 is a means for setting an access right to a user or a user group for each file of the divided HTML source. H
The HTML synthesizing means 5 is means for synthesizing a plurality of divided HTML sources into one HTML source according to the access right of the user. The confirmation processing means 6 is a means for outputting the synthesized HTML source in order to confirm what HTML source is actually generated with the authority of each user. Note that the confirmation processing means 6 may display a Web page based on the HTML source synthesized as necessary.

[0008] The Web page display control device 10 is provided with a WWW on a client terminal (not shown) operated by a user.
It is connected to a browser 7 and a communication line 8. This device is
It works as follows.

When a page request is made from a client terminal, the HTML synthesizing processing means 5 first sets the Web
An HTML file required to display page b is acquired from the configuration information defined in the configuration information definition storage unit 3.

Next, with respect to the divided HTML files necessary for the configuration of a certain page, it is checked in order from the top one whether or not the user who is currently accessing has an access right. As a result of the check, if the file is accessible, the file is used for synthesizing the HTML source sent back to the client terminal. If the file is not accessible, the file is not used. This check is repeated for all the defined files. As a result, only the contents of the file having the access right are taken out, the HTML source of the requested page is synthesized, and transmitted to the client terminal of the requesting user.

As a result, even if the Web page has the same URL, various HTML sources can be created and sent back according to the access right of the accessing user, so that various contents suitable for individual users can be created. Can be displayed.

The confirmation processing means 6 simulates what kind of HTML source is synthesized for each user, and outputs the result to confirm the HTML source for displaying the Web page. . Here, in order to facilitate the confirmation, for example, the names of the divided HTML files used for the synthesis are displayed, and the contents of the HTML source are displayed with a delimiter for each used file.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. First, a Web page display process will be described with reference to FIG.

User information such as users USER1 and USER2 is registered and stored in the user information storage means 2 in advance. User information includes user ID,
Information such as passwords and belonging groups are included.

The same UR is stored in the configuration information definition storage means 3.
L (Uniform Resource Locato
r) Configuration information such as a file name required to compose the page and the name of a user permitted to access each file is defined. For example, as configuration information of page A,
The file names (HTMLa to HTMLd) divided for each part constituting the page A and the names of users who are permitted to access each file are stored. The divided file storage means 1 stores the W
An HTML file constituting the web page is stored.

In this example, of the files HTMLa to HTMLd defined in the page A configuration information, the HTML
As shown in FIG. 3A, the information of the header part of page A, the contents of the item parts “notification” and “new arrival information” are shown in FIG. 3A, and as shown in FIG. As shown in FIG. 3 (C), the content of the item “management information” is HTMLd, and the content of the item “technical information” is HTMLd.
In FIG. 3, information of the footer part is described as shown in FIG.

When the page A is accessed from the WWW browser 7 of the USER 1 via the communication line 8, H
Based on the page A configuration information stored in the configuration information definition storage unit 3, the TML synthesis processing unit 5 converts the files HTMLa to HTMLd constituting the page A into U
Check whether SER1 has access rights. USER1 has access rights only in HTML
a, HTMLb, and HTMLd, the divided file storage unit 1 reads out the HTMLa, H
Only the files of TMLb and HTMLd are acquired, these HTML sources are sent to the transmission buffer, and transmitted to the WWW browser 7 of USER1 via the communication line 8. Therefore, USER1 has header “WELCOME”,
The user will browse page A containing information, news, and management information.

On the other hand, when the page A is accessed from the USER2, the same processing is performed by the HTML synthesizing means 5, and the HTMLa, HTMLc, and HTMLd files to which the USER2 has access right are stored in the divided file. Only these files obtained from the means 1 are sent to the transmission buffer and transmitted to the WWW browser 7 of USER2. Therefore, USER2 includes the header “W
ELCOME ", information, new information, and technical information.

In this manner, different contents can be displayed even on pages of the same URL, depending on the access right of the accessing user. FIG. 4 is a processing flowchart of Web page display.

The Web page display control device 10 waits for an access request (step S1), and if there is a request, an HTM necessary for displaying the page from the requested URL.
An L file is obtained (step S2). Assuming that N = 1 (step S3), the accessing user determines in order from the first file whether or not the Nth file has an access right (step S4). The file is copied to the transmission buffer as an HTML source (step S5). N is incremented by 1 (step S6), and the processing of steps S4 to S6 is performed on all files defined to constitute the page (N = all files defined to constitute the page). Repeat (until file + 1) (step S7). Next, the contents of the transmission buffer are transmitted to the client terminal (step S8).

Next, the setting of the access right to the divided files constituting the page portion will be described. FIG.
FIG. 5 is a diagram showing an example of a page management screen. On the page management screen, the user can change the page information registered for each page, set the access right for the entire page, and set the page layout. here,
Home page and the first to 16th pages
Pages have been created. In FIG. 5, Home: XX division main page and Page 1: What's Ne
For the w page, the access right to the entire page has not been set (shown by a white square in the figure). In this figure, the first page (Page 1) of the page list is displayed, but the second page (Page 1) of the page list is displayed.
Ge2) and thereafter can be displayed by scrolling the screen.

By clicking a "layout setting" button in the page list, an HTML document can be registered for the page, and users and groups who can access the registered HTML document can be registered / deleted. .

FIG. 6 shows a page layout setting screen displayed when a “layout setting” button for a home page (Home) in the page list shown in FIG. 5 is clicked. This homepage (Home: ○
(Business division main page) is composed of frame 1 and frame 2, and the HTML file names used in the header section, item section, and footer section are registered for each of them. To register an HTML file name, use the HT of the item to be registered.
When a triangle button is pressed in the ML file name field, a list of file names of HTML files stored in the divided file storage means 1 in FIG. 1 is displayed. The user can select from the list.

On this page layout setting screen, it is possible to set an access right for each item section constituting a page based on the user information stored in the user information storage means 2. In this example, the file of item part 2 (Home01b.html) and the file of item part 5 (Home02b.ht)
ml) and the file of the item section 6 (Home02c.html) are set with access rights (shown by black squares in the figure).

FIG. 7 shows an example of a screen for setting the access right to the HTML file in the item section. The screen shown in FIG. 7 is displayed by selecting the item section 5 as an access right setting target and clicking an access right setting button on the page layout setting screen shown in FIG.
The setting of the access right to the HTML file of each item part can be performed using the IP address, the user ID, or the group name of the user.

In the access right setting by the IP address,
Enter the IP address in the IP address entry field. Also,
In the access right setting based on the user ID or the group name, the list of accessible users and accessible groups is displayed on the left side of the screen, and the list of inaccessible users and inaccessible groups is displayed on the right side of the screen. After selecting a user name or a group name, the access right is deleted or registered using the delete button and the register button.

In the initial state of setting the access right to the item section, all users and groups are registered in the inaccessible list (all may be registered in the accessible list). The information is obtained from the user information storage unit 2 in FIG.

The header and footer of each page are common to all users and user groups. Therefore, as is clear from the page layout setting screen in FIG. 6, it is not possible to set an access right for the header section and the footer section. Therefore,
The HTML synthesizing means 5 synthesizes the HTML source by using the HTML files constituting the header and the footer regardless of the access right.

FIG. 8 is a flowchart of the access right setting process. It is assumed that the access right setting screen for the item section shown in FIG. 7 is called from the page layout setting screen shown in FIG. The access right setting processing means 4
The following processing is performed. First, as shown in FIG. 6, an IP address that can access this item part and a list of accessible users, inaccessible users, accessible groups, and inaccessible groups are displayed (step S11 in FIG. 8).

Next, if the change button is pressed, the input in the accessible IP address input field is checked.
Change the accessible IP address (step S1
2, S13).

When the user or group registration button is pressed, the selected user or group is taken out of the list of inaccessible users or inaccessible groups and added to the list of accessible users or accessible groups. (Step S14,
S15).

When the user or group delete button is pressed, the selected user or group is taken out from the list of accessible users or accessible groups and added to the list of inaccessible users or inaccessible groups. (Step S16,
S17).

If the setting of the access right is changed, the access right definition information in the configuration information definition storage means 3 is updated (step S18). Steps S11 to S11 are performed until there is a termination instruction such as "return to main", "return to page management", or "return to page layout setting" (step S19).
S18 is similarly repeated.

When the access right is defined, the HTML source actually transmitted to the user can be confirmed by the confirmation processing means 6. Further, a function may be provided so that not only the HTML source but also the actual page display can be checked if necessary.

FIG. 9 shows an example of a confirmation display based on the setting of the access right in the case shown in FIG. In addition, each HTMLa ~
The contents of the HTMLd file are as shown in FIG. FIG. 9A shows an example of an HTML source transmitted to USER1, and FIG.
9 is an example of an HTML source transmitted to USER2, and FIG. 9D is a page display example of USER2.
2 shows an example of page display on the page. When displaying the HTML source, each file used is displayed with a delimiter.
A file name is also added to each.

Such a confirmation display makes it easy to see which HTML file is used for each user, and is convenient for confirming the setting of the access right and investigating a setting error. In this confirmation display, for example, by clicking a field such as “source of frame 1” or “source of frame 2” on the page layout setting screen shown in FIG. 6 is performed.

[0037]

As described above, according to the present invention,
Conventionally, W that required programming such as scripts
Dynamic change of the display contents of the eb page for each user
This can be realized only by making a simple definition using the GUI, and the development cost and operation cost can be significantly reduced. In addition, by having a confirmation display function based on the authority of each user, it is possible to grasp the details of the files and the like that are combined with the HTML source, and to efficiently check the setting of access rights and track mistakes in setting. become able to.
