JP5251717B2 - Real-time web sharing system, real-time web sharing method, and program - Google Patents

Description

  The present invention relates to a real-time web sharing system, and more particularly to a real-time web sharing system capable of sharing the same web page in real time with a plurality of WWW browsers.

  In recent years, with the development of network technology, various technologies have appeared as communication means. In particular, an Internet communication technology called WWW (World Wide Web) is used as a standard technology worldwide.

  In the WWW, an information user (hereinafter referred to as a user) accesses a host computer called a WWW server prepared by an information provider using a program called a WWW browser, and the user acquires desired information. The communication form is taken.

  This information is described in HTML (Hyper Text Markup Language), which is generally composed of character information called a tag. The WWW browser interprets this HTML and displays it on the screen as a Web page. That is, the Web page is a structured document described in HTML.

  In addition to character information and images, tags that allow input operations such as buttons, text input, and item selection can be described on this Web page. A user embeds information in a Web page by performing a click with a mouse or text input from a keyboard on each tag displayed on the WWW browser, and performs an operation generally known as a submit. By carrying out, the content entered on the Web page can be transmitted to the WWW server.

  In addition, link information to other Web pages may be embedded in this Web page. The user can acquire another Web page from the WWW server by operating this link.

  In addition, the Web page on the WWW server can be uniquely specified by a name in accordance with a rule called URL (Uniform Resource Locator). A link on a Web page designates another Web page by having this URL. For example, a URL “http: // server A / path 1 / file 1.html” is a file “file 1.html” under a directory “/ path 1” on “server A” which is a WWW server. A Web page having a descriptor is specified.

  With the spread of personal computers in recent years, more users can access the WWW server on the Internet using the WWW described above, and not only obtain information from the WWW server but also electronic forms via the WWW server. Services such as submission and online shopping are now available.

  However, not all users are familiar with the operation of personal computers and the Internet technology, and there is a problem that there are users who do not know the operation method.

  Therefore, as a technology for supporting users' use of the Internet, Japanese Patent Application Laid-Open No. 2004-178268 (Patent Document 1) synchronizes operations of a plurality of WWW browsers so that users who are far away from each other can be in real time. A Web page sharing system capable of displaying the same WWW browser screen is described.

  Japanese Patent Laid-Open No. 2006-018795 (Patent Document 2) uses a relay server that temporarily receives a Web page acquisition request from a WWW browser in order to synchronize the Web page displayed by the WWW browser in the Web page sharing system. The server acquires a Web page from the WWW server instead of the WWW browser, and distributes the Web page to each WWW browser.

  Japanese Patent Laid-Open No. 2007-193415 (Patent Document 3) restricts synchronization processing of operations for buttons, text input, and the like displayed on a Web page for each WWW browser sharing the same Web page. be able to.

  In JP 2007-193415 A (Patent Document 3), a relay server that acquires a Web page is used instead of the WWW browser, as in JP 2006-018795 A (Patent Document 2).

  In Japanese Patent Laid-Open No. 2007-193415 (Patent Document 3), user attribute information indicating a user of the WWW browser is first set in each WWW browser. Further, in order to limit the synchronization of operations on the entire Web page or the tags in the Web page in the relay server, what operation of each user is limited to the URL of the Web page and the tag in the Web page. Define it.

  When a Web page acquisition request is transmitted from each WWW browser to the relay server to the relay server, the relay server acquires the Web page from the WWW server indicated by the URL included in the acquisition request instead of the WWW browser. To do. The relay server compares the URL of the acquisition request with the URL for which the synchronization of the defined operation is to be restricted, and if they match, adds the operation synchronization restriction information to each tag in the web page or the entire web page, and sends it to the WWW browser. Send.

  In the WWW browser, the operation synchronization restriction information added to each tag or the entire Web page and the user attribute information are used to determine which operation of the WWW browser is restricted, and the user operates the tag. Even if the user does not send the synchronization information to other browsers, the user's input can be concealed.

  In Japanese Patent Laid-Open No. 2002-109147 (Patent Document 4), the user attribute of each browser is divided into a user and an operator, and the user can limit synchronization to any tag in the Web page. When a user operates a tag whose synchronization is restricted, the operation information is not transmitted to the operator.

  When the method described in Japanese Patent Application Laid-Open No. 2007-193415 (Patent Document 3) and Japanese Patent Application Laid-Open No. 2002-109147 (Patent Document 4) is used, a user operates a Web page whose operation synchronization is limited. In this case, the operation is not transmitted to the other WWW browser, and the contents input to the Web page are different. At this time, if the user operates the browser to execute the submission, the input contents of the user included in the Web page acquisition request transmitted from both WWW browsers to the relay server are different, and the WWW further increases from the relay server. Cannot determine how to send an acquisition request when sending an acquisition request to the server.

  In Japanese Patent Laid-Open No. 2002-109147 (Patent Document 4), a user request is transmitted to a WWW server in such a case. However, in this method, when it is necessary to transmit the content operated by the operator to the WWW server, the content cannot be transmitted to the WWW server. In addition, when the contents included in the request are actually different between the user and the operator, it cannot be determined whether the contents are different by intentionally limiting synchronization, or whether the contents are different due to malfunction or erroneous operation.

JP 2004-178268 A JP 2006-018795 A JP 2007-193415 A JP 2002-109147 A

  In a Web page sharing system, when a user operates a Web page whose operation synchronization is limited in the conventional technology, the operation is not transmitted to the other WWW browser, and the contents input to the Web page are different from each other. .

  At this time, if the user operates the browser to execute the submission, the input contents of the user included in the Web page acquisition request transmitted from both WWW browsers to the relay server are different, and the WWW further increases from the relay server. Cannot determine how to send an acquisition request when sending an acquisition request to the server.

  In addition, when the contents included in the request are actually different between the user and the operator, it cannot be determined whether the contents are different by intentionally limiting synchronization, or whether the contents are different due to malfunction or erroneous operation.

  In the present invention, in the WWW browser, a submit detection unit and a combination information adding unit are added, and before the content input by the user from the WWW browser is transmitted to the relay server, the request content in which inconsistency occurs in the relay server In addition to adding binding information instructing that the request can be appropriately combined to the request, when the request by the submission is received from each browser in the relay server, each request is combined from the binding information added in the request combining means. The request is transferred to the Web server.

  A real-time Web sharing system of the present invention includes a WWW server on a network, a WWW browser that acquires and displays a Web page from the WWW server, receives an input to the Web page from a user, and transmits the input to the WWW server, and a WWW A relay server that receives a Web page acquisition request from the browser, acquires a Web page corresponding to the Web page acquisition request from the WWW server, and returns the Web page to the WWW browser.

  A WWW browser displays a Web page on a screen device used by a user and a Web page acquisition unit for acquiring a Web page from a WWW server via a network, and reflects an operation input by the user on the Web page on the screen. In the HTML display means, the transmission / reception means for transmitting the operation information related to the user's operation on the HTML display means to the relay server based on the synchronization restriction designating whether or not synchronization is designated on the Web page, and the HTML display means When the submission of the user's input content by submit occurs, the submit detection means that detects the submission, and the combination that specifies the input content synchronization limitation and the input content combination method at the relay server when the submission is detected A combination information adding unit for adding the combination information corresponding to the instruction attribute to the input content;

  The relay server receives a request from the WWW browser, relays the request to the WWW server, acquires a Web page from the WWW server, and transmits the Web page to the WWW browser, and the WWW browser by the Web page relay unit When the request is received, the binding information added to the request is detected, and when the binding information is added to the request, the request from another WWW browser sharing the Web page is waited, and the Web page is When all the requests from each shared WWW browser are available, the request is combined based on the combination method specified in the combination information to create a combined request, and the Web page relay means is combined with the WWW server. A request combining means for transmitting a request and a WWW bra The operation information transmitted from The comprises the operation information transfer means for transferring to other WWW browsers.

  In the Web page sharing system, it is possible to appropriately transmit the input content whose synchronization is limited regardless of the attribute of the user of the WWW browser to the Web server.

It is a block diagram which shows the structural example of the real-time Web sharing system of this invention. It is a flowchart which shows the process regarding the display of the web page with a WWW browser, and the synchronization of operation on the web page. It is a flowchart which shows the submission process in which input content is transmitted to a relay server. It is a flowchart which shows the process of the relay server when the request from a WWW browser is received. It is a flowchart which shows the process of the relay server when the request from a WWW browser is received.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, the real-time Web sharing system of the present invention includes a WWW server 1, a WWW browser 2, and a relay server 3.

  The WWW server 1 is a server that provides a Web page described in HTML (Hyper Text Markup Language) on a network. Here, HTML will be described as an example, but actually, it is not limited to HTML, and any markup language (Markup Language) for describing a Web page may be used. For example, the Web page may be described in XML (Extensible Markup Language) instead of HTML.

  The WWW browser 2 acquires and displays a Web page from the WWW server 1 on the network, receives an input to the Web page from the user, and transmits it to the WWW server 1. Here, a plurality of WWW browsers 2 are provided. The plurality of WWW browsers 2 may exist on the same computer, or may exist on different computers.

  The relay server 3 relays communication between the WWW server 1 and the WWW browser 2. Here, the relay server 3 receives a Web page acquisition request from the WWW browser 2, acquires a Web page corresponding to the request from the WWW server 1, and returns the acquired Web page to the WWW browser 2. .

  As an example of the WWW server 1, a PC (personal computer), a thin client server, a workstation, a mainframe, a supercomputer, and the like can be considered. However, actually, it is not limited to these examples.

  Examples of a computer having a WWW browser 2 include a PC, a thin client terminal, a workstation, a mobile phone, a car navigation system (car navigation system), a portable game machine, a home game machine, an interactive TV, a digital tuner, a digital recorder, and an information appliance. (Information home application), OA (Office Automation) equipment, etc. can be considered. The computer having the WWW browser 2 may be mounted on a moving body such as a vehicle, a ship, or an aircraft. However, actually, it is not limited to these examples.

  As an example of the relay server 3, a computer having a relay function such as a proxy server, a gateway, or a firewall can be considered. The relay server 3 may be a relay device such as a router or a switching hub, an access point, a base station, or an exchange. Further, the relay server 3 may be a communication device used when the WWW server 1 or the WWW browser 2 performs communication, or an expansion card such as a NIC (Network Interface Card) involved in communication. However, actually, it is not limited to these examples.

  Examples of networks include the Internet, a LAN (Local Area Network), a wireless LAN (Wireless LAN), a cable TV (CATV) line, a fixed telephone network, a mobile phone network, WiMAX, 3G (third generation mobile phone), a dedicated line ( lease line), IrDA (Infrared Data Association), Bluetooth (registered trademark), serial communication line, data bus, and the like. However, actually, it is not limited to these examples.

  The WWW browser 2 includes a Web page acquisition unit 201, an HTML display unit 202, a transmission / reception unit 203, a submit detection unit 204, and a combined information addition unit 205.

  The web page acquisition unit 201 acquires a web page from a server device such as the WWW server 1 through the network.

  The HTML display unit 202 displays the acquired web page on a screen device used by the user. The HTML display unit 202 has a function of reflecting an operation input by a user from an input device such as a mouse or a keyboard on a Web page on the screen.

  The transmission / reception unit 203 acquires an operation of the user on the HTML display unit 202 and transmits operation information to the relay server 3 based on a synchronization restriction that specifies whether synchronization is specified for the Web page.

  The submit detection unit 204 detects the occurrence of transmission of the user input by the submit in the HTML display unit 202.

  When the submission detection unit 204 detects the submission, the combination information addition unit 205 operates the HTML display unit 202 to set the combination instruction attribute that specifies the synchronization limitation of the input content and the combination method of the input content in the relay server 3. Appropriate combination information is added to the input content.

  The relay server 3 includes a Web page relay unit 301, a request combination unit 302, and an operation information transfer unit 303.

  The Web page relay unit 301 receives a request from the WWW browser 2, relays the request to the WWW server 1, and transmits the Web page acquired from the WWW server 1 to the WWW browser 2.

  When the Web page relay unit 301 acquires a request from the WWW browser 2, the request combining unit 302 detects combined information added to the request. When the combined information is added, the request combining unit 302 waits for a request from another WWW browser 2 sharing the same Web page. Thereafter, when all requests from the WWW browsers 2 are prepared, the request combining unit 302 combines the requests based on the combining method specified in the combining information to create a combined request, and the Web page relay unit 301. A connection request to the WWW server 1 is transmitted.

  The operation information transfer unit 303 transfers the operation information transmitted from the WWW browser 2 to each WWW browser 2.

  In addition, since the processing of the Web page acquisition unit 201 and the HTML display unit 202 can be implemented by functions included in a general WWW browser, a description of specific Web page acquisition methods, display methods, and operation methods is omitted. To do.

  In addition, it is assumed that the operation information transmission / reception unit 203, the submit detection unit 204, and the combined information addition unit 205 are implemented using a programming function of a WWW browser. In general, “JavaScript (registered trademark)” , “Java Applet (registered trademark)”, “ActiveX (registered trademark)”, and “Plug-in (registered trademark)”.

  In addition, the WWW browser 2 performs processing such as login in order to identify the user who operates each WWW browser 2, and whether the user operates as a user or an operator with respect to the WWW browser 2. Is added as a user attribute. This login process is a general process in a Web application, and details thereof will not be described here.

  Moreover, as a user, not only a user, an operator, and a system administrator but other users can be assumed.

  Further, FIG. 1 shows two WWW browsers 2 that share the same Web page. However, in reality, the number of WWW browsers 2 is not limited to two, and three or more WWW browsers 2 can simultaneously display the same Web page. You can share the page.

  Furthermore, when the relay server 3 receives a request from each WWW browser 2, it can acquire the above-described user information. This is realized in the WWW browser 2 by adding the above-described user attribute information to the request as additional information generally called a cookie. This process is a general process in a WWW browser, and details thereof will not be described here.

  As described above, each WWW browser 2 can manage user attributes. Further, when the relay server 3 receives a request from the WWW browser 2, the relay server 3 can specify the user of the WWW browser 2.

  Next, the display of a Web page on the WWW browser 2 and the synchronization of operations on the Web page will be described with reference to FIG.

(1) Step S201
The WWW browser 2 acquires a Web page from the relay server 3 using the Web page acquisition unit 201. The WWW browser 2 receives the Web page returned from the relay server 3 by transmitting a request to the relay server 3 as in the normal WWW process. At this time, the relay server 3 receives a request from the WWW browser 2, accesses the WWW server 1, acquires a Web page, and returns it to the WWW browser 2, but the relay server 3 accesses the WWW server 1. In this case, the URL specified for the WWW server 1 may be included in the URL for the relay server 3 by using the method disclosed in Japanese Patent Application Laid-Open No. 2006-018795 (Patent Document 2). May be used to notify the WWW server 1 that accesses the relay server 3.

(2) Step S202
The web page acquisition unit 201 passes the acquired web page to the HTML display unit 202. The HTML display unit 202 displays on the screen according to the HTML described in the Web page.

For example, assume that the HTML of a Web page is described as follows.
*** *** *** *** *** *** *** *** ***
<HTML>
. . . .
<BODY>
Enter the following items.
<FORM METHOD = POST. . . . >
Password: <INPUT TYPE = TEXT NAME = PWD none>
Identification number: <INPUT TYPE = TEXT NAME = IDNM cause>
Address: <INPUT TYPE = TEXT NAME = ADDR>
Age: <INPUT TYPE = TEXT NAME = YR>
Special Notes: <INPUT TYPE = TEXT NAME = EXT loop send>
<INPUT TYPE = SUBMIT. . . >
</ FORM>
</ BODY>
</ HTML>
*** *** *** *** *** *** *** *** ***

  In this HTML description, "PWD", "IDNM", "ADDR", "YR", and "EXT" are defined as tags for inputting text, and correspond to password, identification number, address, age, and special notes, respectively. doing. In addition, a submit button for executing submit for transmitting the input content is finally defined.

  In addition, the “IDNM” tag, “PWD” tag, and “EXT” tag describe synchronization restriction attributes of “none”, “nouser”, and “noop” that specify synchronization restriction. This indicates that the synchronization of operations with respect to each tag is restricted when two users, ie, a user and an operator, are assumed as users.

  “None” is asynchronous designation and indicates that the contents operated by both the user and the operator are not synchronized.

  “Nouser” is user asynchronous designation and indicates that the contents operated by the user are not synchronized.

  “Noop” is an operator asynchronous designation and indicates that the contents operated by the operator are not synchronized.

  Accordingly, the password in the above-described HTML description example is not synchronized regardless of whether it is operated by the user or the operator. In addition, the identification number in the above-described HTML description example is not synchronized with the content entered by the user, but can be confirmed by the user in synchronization with the user when entered by the operator. In addition, the special instructions can be confirmed by the operator when the user inputs, but the contents input by the operator can be kept secret from the user. Since other addresses and ages are not restricted, the input contents are synchronized between the operator and the user.

  This tag attribute may be described directly on the Web page in the WWW server 1, or an HTML page on the relay server 3 using the technique disclosed in Japanese Patent Application Laid-Open No. 2007-193415 (Patent Document 3). A description may be added.

  Further, the above description of the synchronization restriction attribute is an example, and other character strings may be designated.

  Further, the designation method is not a tag attribute, but there are other methods such as describing as a comment and a tag not displayed, but this method is not limited here.

(3) Step S203
At this time, the operation information transmission / reception unit 203 confirms whether or not the user has operated the tag.

(4) Step S204
When the user performs an operation on the above tag, the operation information transmission / reception unit 203 acquires event information for the operation.

(5) Step S205
The operation information transmission / reception unit 203 confirms whether the synchronization restriction attribute is specified for the tag in which the event has occurred due to the user's operation or the like (the tag from which the event has occurred).

(6) Step S206
The operation information transmission / reception unit 203 transmits the operation information to the relay server 3 when the synchronization restriction attribute is not designated.

(7) Step S207
The operation information transmitting / receiving unit 203 compares the user attribute set in the WWW browser 2 when the synchronization restriction attribute is designated. That is, the operation information transmission / reception unit 203 confirms with the user of the WWW browser 2 whether synchronization is restricted.

(8) Step S208
The operation information transmission / reception unit 203 transmits the operation information to the relay server 3 when the synchronization is not limited.

(9) Step S209
When the synchronization is restricted, the operation information transmission / reception unit 203 stops transmitting the operation information of the operation.

  In step S207 and step S208, when the WWW browser 2 transmits the operation information to the relay server 3, the relay server 3 transfers the operation information to another WWW browser 2 by the operation information transfer unit 303.

  When the operation information transmission / reception unit 203 acquires the operation information, the other WWW browser 2 operates the HTML display unit 202 and executes the synchronization process according to the operation information.

Now, it is assumed that, for example, an operator has the following input contents by the above processing.
*** *** *** *** *** *** *** *** ***
Password: (no entry)
Identification number: 123456
Address: Minato-ku, Tokyo Age: 20
Special notes: 0x-xx-xxxx is requested to contact the telephone. Request slip ABCD.
*** *** *** *** *** *** *** *** ***

In addition, it is assumed that the following input content is made by the user.
*** *** *** *** *** *** *** *** ***
Password: password
Identification number: -123456
Address: Minato-ku, Tokyo Age: 20
Special note: Telephone required ************************************

  The submit process in which the above contents are transmitted to the relay server 3 at this time will be described with reference to FIG.

(1) Step S301
A user such as a user or an operator presses a submit button in a Web page displayed on the screen device by the HTML display unit 202 on the WWW browser 2, or the submit is called by a program such as “JavaScript (registered trademark)”. Thus, the submit process is started. When the submit process is started, the operation information transmission / reception unit 203 transmits the operation to the other WWW browser 2. In this case, the other (the other) WWW browser 2 also starts the submission process.

(2) Step S302
At this time, the submit detection unit 204 on the WWW browser 2 detects the start of the submission and instructs the combined information adding unit 205 to add combined information.

(3) Step S303
The combined information adding unit 205 operates the HTML display unit 202 to search for a tag with a synchronization restriction attribute in the Web page.

(4) Step S304
Here, when there is no tag with the synchronization restriction attribute, the combined information adding unit 205 executes a normal submit process.

(5) Step S305
When there is a tag with a synchronization restriction attribute, the combined information adding unit 205 adds a combined information character string before the original tag name.

  This combined information character string is a character string that instructs the relay server 3 whether or not the input content should be transmitted to the WWW server 1 in accordance with user attributes such as users and operators. For example, when transmitting the operator input content to the WWW server 1, the combined information adding unit 205 designates “_o_” as the combined information character string, and when transmitting the user input content to the WWW server 1, “_u_ "Is specified in the combined information string.

  For example, the WWW browser 2 transmits user information according to a tag having synchronization restriction attributes of “none” and “noop”, and transmits operator information according to a tag having “nouser”. Shall. In this case, in the above, the names of the tags “PWD”, “IDNM”, “ADDR”, “NM”, “EXT” are “_u_PWD”, “_o_IDNM”, “ADDR”, “NM”, “_u_EXT”. "

  Further, at this time, the combination information adding unit 205 checks whether each tag has a combination instruction attribute. The combination instruction attribute can directly indicate whether the input contents of the operator or the user are transmitted.

  Further, the combined information adding unit 205 changes the combined information character string of the tag name according to the combined instruction attribute. For example, the operation information transmission / reception unit 203 changes the name of the tag to “_o_EXT” because the “EXT” tag has a combination instruction attribute “sendop”. At this time, the combined information adding unit 205 does not directly change the name of each tag, but adds and specifies the name of the tag after the change to the additional information transmitted together with the request transmission such as a cookie. It doesn't matter.

(6) Step S306
As described above, the combined information adding unit 205 changes the name of each tag, and when the submission is processed in the WWW browser 2, the changed name of each tag is added to the request as a parameter together with its value. This process is a general process in the WWW browser 2.

  Thereby, in the example of the HTML description described above, the operation information transmitting / receiving unit 203 transmits the following URL to the relay server 3 from the operator.

・ URL
"Http: // relay server /...?_ u_PWD = & _ o_IDNM = 123456 & ADDR = Minato-ku, Tokyo & YR = 20 & _o_EXT = 0x-xxx-xxx. Request slip ABCD."

  In the example of the HTML description described above, the operation information transmitting / receiving unit 203 transmits the following URL to the relay server 3 from the user.

・ URL
"Http: // relay server /...?_ u_PWD = password & _o_IDNM = -123456 & ADDR = Minato-ku, Tokyo & YR = 20 & _o_EXT = phone required"

  The above is an example using a method called “GET” that generally designates input contents in a URL in the submit process, but a method called “POST” that designates input contents in a request may be used. Absent.

  Next, processing of the relay server when a request from the WWW browser 2 is received will be described with reference to FIGS. 4A and 4B.

(1) Step S401
The web page relay unit 301 of the relay server 3 receives the request including the above-described combined information character string. Then, the Web page relay unit 301 passes the request to the request combining unit 302.

(2) Step S402
When the request combining unit 302 receives a request from the Web page relay unit 301, the request combining unit 302 checks whether all requests from users (users of each WWW browser) such as an operator and a user have been received.

(3) Step S403
If all the requests from each user are not received, the request combining unit 302 waits until all the requests are received.

(4) Step S404
The request combining unit 302 receives all the requests of each user. When the requests of each user are prepared, the request combining unit 302 creates a combined request having only the URL for the WWW server 1 excluding parameters from the requests of each user. That is, the request combining unit 302 creates a combining request that does not have a parameter that specifies the URL of the WWW server 1.

(5) Step S405
Next, the request combining unit 302 acquires the parameter of each user's request for each parameter name.

(6) Step S406
The request combining unit 302 confirms whether a combined information character string is specified for the parameter name.

(7) Step S407
When the combined information character string is specified in the name of the parameter, the request combining unit 302 specifies the user who is instructed to transmit the combined information character string. That is, the request combining unit 302 specifies the user who has instructed transmission based on the combined information character string.

(8) Step S408
The request combining unit 302 deletes the combined information character string from the user parameter.

(9) Step S409
The request combination unit 302 adds a parameter from which the combination information character string has been deleted to the combination request. That is, the request combining unit 302 adds the specified user parameter to the combining request.

  For example, in the above-described HTML description example, the request combining unit 302 adds the “_u_PWD” parameter that is the user parameter to the request of the Web server 1, and the “_o_IDNM” parameter and the “_o_EXT” parameter that are the operator parameters. Is added to the request of the Web server 1.

(10) Step S410
In addition, when the combined information character string is not specified in the parameter name, the request combining unit 302 confirms whether the parameter values of all users match in the parameter.

(11) Step S411
If the parameter values of all users match in the parameter, the request combining unit 302 adds the parameter as it is to the combining request.

(12) Step S412
The request combining unit 302 notifies each user that an abnormality has occurred when the parameter values of all the users do not match in the parameter.

  At this time, a method of notifying abnormality by returning a Web page to the WWW browser 2 or a method of notifying abnormality as operation information using the operation information transfer unit 303 can be considered, but this method does not matter.

(13) Step S413
The request combining unit 302 confirms whether all parameters have been processed. When the request combining unit 302 has not processed all the parameters, the request combining unit 302 executes the processes in steps S406 to S412 for all the parameters.

  As described above, for example, in the example of the HTML description described above, the following join request is created.

Join request “http: // WWW server / ...? PWD = password & IDNM = 1123456 & ADDR = Minato-ku, Tokyo & YR = 20 & EXT = 0x-xxx-xxxx Request for telephone contact. Request slip ABCD.”

(14) Step S414
The request combining unit 302 passes a combination request to the Web page relay unit 301 when all parameters have been processed. The Web page relay unit 301 transmits a combination request to the WWW server 1.

  In the WWW server 1, processing is executed in the same way as normal access, and a Web page is returned to the relay server 3.

  When the Web page relay unit 301 of the relay server 3 acquires the Web page, it returns a Web page to each WWW browser 2.

  As described above, it is possible to instruct the relay server to transmit a parameter designating a user such as a user or an operator for the input content for which synchronization restriction is set on the Web page.

  Further, even when a different value is requested for a parameter that is not subjected to synchronization restriction, it is possible to determine whether it is due to synchronization restriction, error transmission, or error processing.

  As described above, in the present invention, in the WWW browser, the submit detection unit and the combined information addition unit are added, and before the content input by the user from the WWW browser is transmitted to the relay server, the relay server does not match. Is added to the request to instruct the request contents to be appropriately combined, and when the request by the submission is received from each browser in the relay server, from the combined information added in the request combining means, respectively Are combined, and the request is transferred to the Web server.

  The WWW browser acquires and displays a Web page from a WWW server on the network, receives an input to the Web page from a user, and transmits it to the WWW server.

  The relay server receives a Web page acquisition request from the WWW browser, acquires a Web page corresponding to the request from the WWW server, and returns it to the WWW browser.

  The WWW browser includes Web page acquisition means, HTML display means, transmission / reception means, submit detection means, and combined information addition means.

  The Web page acquisition unit acquires a Web page from a server device such as a WWW server through the network.

  The HTML display means has a function of displaying the acquired Web page on a screen device used by the user and reflecting an operation input by the user from the input device on the Web page on the screen.

  The transmission / reception means acquires the user's operation on the HTML display means, and transmits the operation information to the relay server based on the synchronization restriction that specifies whether or not synchronization is specified for the Web page.

  The submit detection means detects the occurrence of transmission of the user input by submit in the HTML display means.

  When the submission information is detected, the combined information adding unit operates the HTML display unit to add combined information corresponding to the combination instruction attribute specifying the synchronization limitation of the input content and the combination method of the input content at the relay server to the input content.

  At this time, when the submit process is started in the WWW browser, the submit detection unit detects the start of the submission and instructs the combined information adding unit to add the combined information.

  Further, the combined information adding means operates the HTML display means to search for input contents (input contents with synchronization restrictions) in which synchronization restrictions are specified in the Web page.

  The combined information adding means executes normal submit processing when there is no input content with synchronization restriction.

  When there is an input content with a synchronization restriction, the combination information adding means receives it from a plurality of users based on the synchronization restriction and a combination instruction specified accompanying it before the name of the original input content. Add the combined information character string that instructs the relay server which user's input content is sent as a request to the WWW server among the input content, and relay each input content in the form of parameters of name and value Send to server.

  The relay server includes a Web page relay unit, a request combination unit, and an operation information transfer unit.

  The Web page relay unit receives a request from the WWW browser, relays the request to the WWW server, and transmits the Web page acquired from the WWW server to the WWW browser.

  When the request combining unit acquires the request from the WWW browser by the Web page relay unit, the request combining unit detects the combined information added to the request.

  When combining information is added, the request combining unit waits for requests from other WWW browsers sharing the same Web page, and waits until all requests from each WWW browser are transmitted.

  When all the requests are ready, the request combining unit generates a combined request by combining the requests based on the combining method specified in the combined information, and transmits the combined request to the WWW server via the Web page relay unit. To do.

  The operation information transfer means transfers the operation information transmitted from the WWW browser to each WWW browser.

  When the Web page relay unit of the relay server receives a request including the combined information character string, it passes the request to the request combining unit.

  When receiving the request from the Web page relay unit, the request combining unit waits until all the requests of each user are received.

  The request combining means creates a combined request having only the URL for the WWW server, with the parameters omitted from each user's request, when each user's request is complete.

  The request combining unit acquires the parameters of each request for each parameter name, and confirms whether a combined information character string is specified for the parameter name.

  When a binding information string is specified in the parameter name, the request binding means identifies the user who is instructed to send the binding information string and deletes the binding information string from the user's parameter To the join request.

  The request combining unit checks whether or not the parameter values of all users match in the parameter when the combination information character string is not specified in the parameter name.

  When the parameter values of all users match, the request combining unit adds the parameters as they are to the combining request.

  If the parameter values of all users do not match, the request combining unit notifies each user that an abnormality has occurred and ends the process.

  The request combining unit performs processing for all parameters, and then passes the combination request to the Web page relay unit.

  The Web page relay means transmits a combination request to the WWW server.

  As mentioned above, although embodiment of this invention was explained in full detail, actually, it is not restricted to said embodiment, Even if there is a change of the range which does not deviate from the summary of this invention, it is included in this invention.
