A means (4, 11 in FIG. 1) for sending an HTML file or an intermediate code file according to the result of the mode determination means or a mode which can be supported by the Web server; Session end determination means (12 in FIG. 1). Each of the above-mentioned means is controlled by a program executed by the local host computer to control the Web.
It can be realized as server software.

In an embodiment of the present invention, in a computer network constituted by a Web server and a local host, an intermediate code file and an HTML file are held in the Web server, and when a file download request is issued (a communication session is established). At the time of establishment)
It is determined whether the Web browser on the local halt is compatible with the intermediate code, and a file corresponding to the mode of the Web browser is sent. The Web browser also determines whether the transmitted file is an intermediate code or an HTML file, and if the file is an intermediate code, skips processing such as HTML language analysis and immediately performs display processing.

According to the embodiment of the present invention, by reducing the size when transferring the intermediate code file,
Since it is not necessary to shorten the communication time due to the transfer and to perform processing such as analysis, the processing time can be reduced, and the display time of the Web browser can be reduced.

In the system according to the embodiment of the present invention, it is possible to coexist with both currently distributed Web server and browser software.

In order to describe the above-described embodiment of the present invention in more detail, embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing a Web in one embodiment of the present invention.
FIG. 3 is a diagram for explaining an operation of a local host 102 connected to a server 101 via a network 103. Web server software is mounted on the Web server 101, and a Web browser is mounted on the local host 102 and operates.

First, the case where the intermediate code file is transferred will be described.

When a session is established, a corresponding mode code is sent from the Web browser to the Web server software by the corresponding mode code sending means 1.

The web server software obtains the corresponding mode according to the corresponding mode code obtaining means 2.

Then, the corresponding mode code determining means 3 determines whether the file is an HTML file or an intermediate code file. If the file is an intermediate code file, the intermediate code file sending means 11 is activated.

The file sent from the intermediate code file sending means 11 is obtained by the file obtaining means 5 of the Web browser.

In the Web browser, the file is checked, and if a character string "mode 1" is found at the beginning of the file, the file is processed as an intermediate code by the intermediate code analyzing means 9 and displayed on the homepage. The screen is output by the means 10.

FIG. 2 shows an example of an HTML file.

FIG. 3 shows an example of the intermediate code file of the HTML document shown in FIG. 2 (see FIG. 3A) and a conversion example (see FIG. 3B). For example, the <HTML> tag indicating the beginning of the document is converted to a code such as “01”, and the </ HTML> tag indicating the end of the document is converted to a code such as “−1”. In FIG. 3, the binary code is also displayed in text for easy viewing.

Referring again to FIG. 1, the intermediate code file is generated by a suitable converting means from the language file example of FIG. 2, for example, as shown in FIG. 3 (A).

In the example shown in FIG. 2, while the size of the original HTML file is 184 bytes, FIG.
The size of the intermediate code file shown in (A) can be compressed to about half the size of 95 bytes.

Next, consider a case where only the Web server does not support the intermediate code.

In this case, referring to FIG. 1, first, the corresponding mode code is sent by the corresponding mode code sending means 1. However, since the Web server does not have the processing function, the requested HTML file is replaced with the HTML file. It is sent out by the sending means 4 as it is.

In the Web browser, the file is determined by the mode determining means 6, and since there is no identifier "mode 1" at the beginning, the file is determined to be an HTML file,
The intermediate code file is generated through the file analysis unit 7 and the intermediate code generation unit 8.

Then, the display is performed by the homepage display means 10 by the intermediate code analysis means 9.

Next, consider the case where the Web browser does not support the intermediate code.

In this case, since the corresponding mode code transmitting means 1 does not exist, the Web server sets the corresponding mode code in HTML, and sets the HTML file transmitting means 4.
Sends an HTML file.

The Web browser processes and obtains the obtained HTML file in the same manner as in the conventional method.

As described above, in this embodiment, the web server software currently used on the Internet,
It can be used together with browser software, and among those that support intermediate codes, it is possible to improve the display performance compared to the conventional method.

[0036]

As described above, according to the present invention,
The transfer data (the number of transfer bytes) between the server and the local host can be reduced, so that the display speed can be improved by reducing the file transfer time and the processing time.

Further, according to the present invention, there is an effect that software on a Web server and Web browser software which have been generally used conventionally can be used together.
