Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a web
The present invention relates to a method for storing data, and more particularly, to a method for storing dynamic web data.

[0002]

2. Description of the Related Art As dynamic web data, for example, C
Dynamic pages linked with external applications using GI (Common Gateway Interface) and ASP (Ac
tive Server Pages).

[0003] CGI is an application cooperation function provided in a WWW (World-Wide-Web) server. W
A WW server usually simply sends back a file such as a text or image for which a transfer request has been made to a display browser (web browser) side. However, if a CGI is used, the WW server cooperates with an external application and transmits the result. It can be sent back to the browser. For example, the latest information can be updated by calculating the number of accesses in cooperation with the script language Perl.

[0004] ASP is Microsoft's W
This is a web page using technology such as VB script (Visual Basic Scripting edition) that makes a static page dynamic provided in the WW server.

[0005] VB script is a subset of Microsoft's VBA (Visual Basic for Apprication) and is a scripting language that runs on Microsoft's WWW browser. HTML (Hyper Text Marku
By embedding and describing a <Script> tag in a (p Language) file, event processing on a WWW browser can be executed. Microsoft's IIS (Internet Information Server) on the WWW server side
By using r), a VB script on the server side can be executed, and a dynamic homepage (ASP) can be created.

[0006]

When a display browser is set to offline work and a previously opened page is browsed via a network such as a LAN, the browse is performed if the page is a static page made of HTML or the like. it can.

[0007] However, if the page is a dynamic page linked with an external application using CGI or a dynamic page created by ASP, it cannot be browsed completely.

Conventionally, when dynamic web data such as numerical values in a database which dynamically changes via a web service such as CGI or ASP is searched, a data date / time comparison function of a display browser is activated, and a cache area in the browser is searched. This is because the inquiry result data via the CGI or the ASP is not stored.

[0009] Although the information in the database often changes only once a day, it is necessary to inquire the dynamic database each time.

For this reason, these dynamic display data are
Every time web data was queried from the browser software, it was necessary to load the latest data from the web server via the network.

SUMMARY OF THE INVENTION An object of the present invention is to solve the problem of the prior art that dynamic web data cannot be stored in the cache area of a display browser. An object of the present invention is to provide a method of storing web data which can display information without executing an inquiry again via a network.

[0012]

In order to solve the above problems, the present invention provides a method for displaying dynamic web data by adding date and time information to a packet of the dynamic web data when browsing the web data. Automatically stored in a cache area in the storage area.

According to the present invention, dynamic web data which is not conventionally stored in the cache area of the display browser software can be easily and automatically stored in the cache area.
Once the dynamic data is captured, the information can be easily browsed without having to execute the query again via the network.

Embodiments of the present invention will be described below in detail with reference to the drawings.

First Embodiment A configuration according to a first embodiment of the present invention will be described.

FIG. 1 is a diagram showing a configuration of a method for storing web data according to the first embodiment.

In the first embodiment, the following software modules are used.

Display browser (software in terminal device) Web server (software in server) CGI or ASP (software in server) COM (Component Object Model) ... (software in server) Database (Software in server) Web server filter (Software in server) Caching means in display browser (Software in terminal device) The standard modules usually used for the Internet or intranet communication are as described above, However, in the first embodiment, a module for performing a unique control operation is additionally used.

The operation in the first embodiment, that is, control procedures A to F for ordinary Internet or intranet communication will be described below.

A Access a specific homepage address in the web server from the display browser.

B: The web server executes a script file using CGI or an ASP control program for querying the database for the data of the home page inquired from the Internet browser.

A database connection communication module (COM) corresponding to communication from a script file or a control program of an ASP using a CGI from the C web server is started.

D Database connection communication module (C
In response to an inquiry from the OM), the latest data corresponding to the inquiry is extracted from the database, and the value is passed to the database connection communication module (COM).

E Hereinafter, data is delivered in the order of the database connection communication module (COM) → the script file using the CGI or the control program of the ASP → the web server → the display browser, and the data is displayed on the screen by the display browser. At this time, conventionally, since the dynamic web data packet from the web server has not been accompanied by date and time information, the display browser does not store these dynamic data in its own cache area, but sends the dynamic data to the web server. The above operations A to E were executed each time the dynamic data inquiry was performed.

F In the first embodiment, in the above-mentioned E operation, the dynamic data transmission section of the web server adds a module for artificially adding specific date and time information to the dynamic web data packet. The browser is caused to execute processing for storing these dynamic data in its own cache area.

Thus, the information of the dynamically changing dynamic database is stored in the display browser, and even if the network between the web server and the display browser is disconnected, the data stored in the cache area in the display browser is stored. , The dynamic data screen at the time of the previous inquiry can be easily displayed.

In other words, the conventional dynamic database query in the web environment is controlled so that the query result data is not stored in the cache area of the display browser as in the above-described operation. Even if you take your terminal outdoors and
When the AN communication is interrupted, it is impossible to browse the contents because there is no data in this cache area.

In the first embodiment, in order to overcome this, the date and time information is artificially added to the reply data packet so that the data packet is automatically stored in the cache area of the display browser. This makes it possible to easily search data outdoors or the like without installing special data storage software on the terminal device.

The date and time information includes the year, month, day, day of week, hour,
It consists of minutes and seconds (Greenwich Mean Time). When importing a dynamic file, this date and time information is programmatically added by a filter (module),
The client recognizes the file as a new file and automatically saves it in a temporary memory area, that is, a cache area.

Second Embodiment A configuration according to a second embodiment of the present invention will be described.

FIG. 2 is a diagram showing a configuration of a web data storage method according to the second embodiment.

In the second embodiment, the following software modules are used.

Display browser (software in terminal device) Web server (software in server) CGI or ASP (software in server) COM (Component Object Model) ... (software in server) Database (Software in server) Caching means in display browser ... (Software in terminal device) HTML conversion means of database information ... (Software in server) HTML file indrawing means in display browser ...
(Software in Terminal Device) The standard modules normally used for Internet or intranet communication are as described above, but in the second embodiment, a module for performing a unique control operation is additionally used.

The operation in the second embodiment, that is, control procedures A to E for ordinary Internet or intranet communication will be described below.

A Access a specific homepage address in the web server from the display browser.

B The web server executes a script file using CGI or an ASP control program for querying the database for the data of the home page inquired from the Internet browser.

A database connection communication module (COM) corresponding to communication from a script file or a control program of an ASP using a CGI from the C web server is started.

D Database connection communication module (C
In response to an inquiry from the OM), the latest data corresponding to the inquiry is extracted from the database, and the value is passed to the database connection communication module (COM).

E Hereinafter, data is delivered in the order of the database connection communication module (COM) → the script file using the CGI or the control program of the ASP → the web server → the display browser, and the data is displayed on the screen by the display browser. At this time, conventionally, since the dynamic web data packet from the web server has not been accompanied by date and time information, the display browser does not store these dynamic data in its own cache area, and sends the dynamic data to the web server. The above-described operations A to E were executed each time a static data inquiry was made.

F In the second embodiment, in the above-mentioned E operation, a module for converting the database information into HTML is added at the database connection communication module (COM), so that these dynamic data can be stored in the server device in HTML. And execute the process of storing.

Thereafter, when the HTML file in-browser in the display browser is operated to pull in the HTML data in the server into the browser, the date and time comparison means in the browser is activated and the dynamic data is stored in the cache area in the browser. Is accumulated.

Thus, also in the second embodiment,
Just as in the first embodiment, even when the network between the web server and the display browser is disconnected, the data stored in the cache area in the display browser can be used.
The dynamic data screen at the time of the previous inquiry can be easily displayed.

Although the present invention has been specifically described based on the embodiments, the present invention is not limited to the above-described embodiments, and it is needless to say that various changes can be made without departing from the gist of the present invention. It is.
