DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a computer and a computer system. For details, refer to Wor through a network and the Internet.
The present invention relates to a method of using resources of ld Wide Web (hereinafter abbreviated as WWW) (media information such as a document, an image, and a sound), and particularly to a method of searching for resources.

[0002]

2. Description of the Related Art First, a general technique relating to the WWW will be described. WWW is a Web service that provides resources (media information such as documents, images, sounds, etc.) existing on the network.
b server and a Web browser for extracting resources. The Web server is a program executed on the server computer, receives a request from the Web browser, searches for the requested resource, and returns it to the Web browser. The Web browser is a program executed on the client computer. The Web browser remotely connects to the Web server, specifies and requests a specific resource, and
Displays resources received from the server. Resources displayed on the Web browser are HTML (Hyper Text Markup Language)
e) Expressed as a page written in a language.

[0003] The HTML language is a language for designating page layouts and hyperlinks, and defines the syntax of dedicated embedded instructions and the location of resources.
For more information on HTML, see ISBN 4-900900-332-X, published on April 30, 1997, released by Ohm Co., Ltd., author Stephen
See Spainhour, Valerie Quercia, translator Shigeya Tanabe, book name "WEBMASTER Quick Reference".

Next, a conventional technique of a Web application execution method will be described. A Web application is implemented as a set of linked pages. Upon receiving the page requested by the Web server, the Web browser proceeds with the processing of the Web application by sequentially requesting another page in accordance with the designation of the hyperlink described in the received page. By the way, image data or audio data included in a page requested by a Web browser to a Web server is generally large data in many cases. Therefore, when the bandwidth of the communication path from the Web browser to the Web server is small, it takes a long time from when the Web browser requests a page to the Web server to when the entire data of the requested page is completely received from the Web server. Cost. As a conventional technique for solving this problem, an information processing system disclosed in Japanese Patent Application Laid-Open No. 9-34772 has been proposed. This is called Known Example 1. In the first known example, a relay device is placed on a network connecting a server computer to a client computer, and a technology for reducing the data amount of image data in the present relay device is patented.

[0005]

A problem to be solved by the present invention is that when a Web application is executed,
When a Web browser executed on a client computer requests a page from a Web server executed on a server computer, the contents of data returned by the Web server to the Web browser can be actually output by the client computer. This is the same regardless of the data format.
For this reason, the Web server may return to the Web browser redundant data that cannot be actually output by the client computer.

More specifically, a case where image data including color information is returned to a client computer having only a monochrome display output device, or audio data is returned to a client computer having no audio output device. Is mentioned. In such a case, W
When the bandwidth of the communication path to the web server is narrow, the time consumed from when the web browser requests a page to the web server until the page is completely received is compared with the amount of data actually output. It will be long. The present invention aims to solve the following problems with respect to such a problem.

(1) A server computer manages a data output function for each model of a client computer, and, according to the model of the client computer, a content including only data that can be actually output by a client computer to a requested page. And implements a mechanism for sending back to the client computer.

[0008]

In order to solve the above problems, the present invention comprises a step of obtaining a computer model from a file on a client computer and a step of transmitting the computer model to a server computer. ing. Further, receiving the computer model from the client computer, and using the computer model as a key,

0, the requested page is read, and among the description contents of the read page, a result obtained by performing a conversion process on the description content of reading an image file or an audio file is written in a work file. showed that. In step 1201, the contents of the page requested by the Web browser are read from the page file 112 stored in the external storage device 104 to the main storage device 103. A process 1202 generates an empty work file in the external storage device 104. A process 1203 initializes the control variable i with 0. The value of the control variable i indicates the line number of the read page. The process 1204 adds 1 to the control variable i. A process 1205 fetches the statement on the i-th line of the read page and stores the temporary variable
Set to LINE.

Hereinafter, the processing 1206 and the processing 1207 are as follows.
This is a processing step of determining the description content of the statement on the i-th line set in the temporary variable LINE. Processing 12
In step 06, it is determined whether or not the content of the temporary variable LINE is a tag for reading an HTML image file. If true, the process proceeds to step 1210; if false, the process proceeds to step 1207. In the process 1210, a conversion process related to the display output function is performed on the contents of the temporary variable LINE, and the process proceeds to the process 1208. The detailed flow of the processing 1210 is shown in FIG. The processing 1207 is performed by using the temporary variable LI
It is determined whether or not the content of the NE is a tag for reading an HTML audio file. If true, process 1211
If it is false, the process proceeds to the process 1208.

In the processing 1211, the contents of the temporary variable LINE are converted with respect to the sound output function,
Proceed to 08. The detailed flow of the processing 1211 is shown in FIG. A step 1208 writes the contents of the temporary variable LINE next to the last line of the work file. Process 1209
Determines whether the value of the control variable i matches the line number of the last statement of the read page. If they match, the process ends. If they do not match, the process returns to step 1204.

FIG. 13 shows a process 1210 shown in FIG. 12 for converting a statement relating to the display output function.
The detailed flow of was shown. Prior to this flow, in the process 1004 shown in FIG. 10, a character string indicating the display output function of the client computer is set in the temporary variable display. In the processing 1205 shown in FIG. 12, the statement on the i-th line of the page requested by the Web browser program 130 is set in the temporary variable LINE. In the example of page 1101 shown in FIG. 11, the statement to be processed in this flow is line 11
It is 10. Therefore, "<IMG src =" htt
p: //www.sample.co.jp/Image01 ">” is set.

A process 1301 determines whether or not the value of the temporary variable display is "full color". If the determination result is true, the process proceeds to step 1304;
The process transitions to 302. In processing 1304, the contents of the temporary variable LINE are read as a statement for reading the image file 115 having full-color color information stored in the directory 114, that is, “<IMG src =" http: //www.sample.c
o.jp/FullColor/Image01 ">” and finish the process.

A process 1302 determines whether or not the value of the temporary variable display is “64K color”. If the determination result is true, the process proceeds to step 1305;
The process is shifted to 3. In processing 1305, the temporary variable LI
64, stored in the directory 116,
A statement for reading an image file 117 that has been subjected to data compression so as to have color information of up to a thousand colors, ie, “<IMG
src = "http://www.sample.co.jp/64K/Image01">", and the processing ends.
It is determined whether or not the value of lay is “monochrome”. If the result of the determination is true, the process proceeds to step 1306; otherwise, the process ends.

Step 1306 is a process for changing the contents of the temporary variable LINE to
A statement for reading the monochrome image file 119 stored in the directory 118 and subjected to data compression with a higher intensity than the image file 117 by removing the color information, ie, “<IMG src =" http://www.sample.co. .jp / Mono / I
mage01 ">" and the process ends. According to the above processing, when the Web browser program 130 requests the Web application execution system for a page for reading an image file including color information that cannot be displayed on the client computer 121, the color information is reduced to reduce the data amount. It is possible to return a page modified to read the reduced image file to the Web browser program 130. As a result, it is possible to reduce the consumption time from when the Web browser program 130 requests a page to the Web application execution system to when the page is completely received and displayed on the display output device 128.

FIG. 14 shows a detailed flow of the processing 1211 in FIG. 12 for converting a statement relating to the voice output function. Prior to this flow, in a process 1004 shown in FIG. 10, a character string indicating the audio output function of the client computer is set in the temporary variable sound. In the processing 1205 shown in FIG. 12, the statement on the i-th line of the page requested by the Web browser program 130 is set in the temporary variable LINE. FIG.
In the example of page 1101 shown in FIG. 1, the statement to be processed in this flow is line 1109. Therefore, "<BGSOUND src =" http: //www.sample.c
o.jp/Sound01 ">” is set.

The process 1401 determines whether or not the value of the temporary variable sound is "OK". If the determination result is true, the process ends without performing the description content conversion process, and if the determination result is false, the process is shifted to process 1402. The process 1402 determines whether or not the value of the temporary variable sound is “NG”. If the result of the determination is true, the process proceeds to step 1403; otherwise, the process ends.

In step 1403, an empty character string "" is set in the temporary variable LINE, and the process ends. By the above processing,
When the web application execution system receives a page request from the web browser program 130 on the client computer 121 having no voice output function, the web browser program 130 changes the page modified so that the voice file is not read.
