2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Application Laid-Open No. H10-105514, when a homepage is accessed in a part of a WWW browser display area of a computer connected to the Internet to view the homepage. Data that needs to be updated frequently, such as news information, is stored in HTML (Hy
per Text Markup Language
s) There was a technique to change the syntax without changing it.

In a conventional device using a network, as shown in FIG. 9, a personal computer or a PDA (Pers.
Since the online data assistants (personal digital assistants) connect to a network such as the Internet by using a server machine as a terminal, the terminal must be connected to the server machine via a communication circuit, a LAN cable, or the like. . In order to operate the homepage, HTML created on the personal machine by the individual
Everything relied on the server machine, such as being able to view it on the Internet without uploading the file to the server machine.

Further, a mechanism called CGI, which starts an external program from HTML in a WWW server system and returns the result to a WWW client, is often used. As shown in FIG. 10, the processing flow of the CGI is as follows. First, the UR described in the HTML file by the WWW browser 81 on the terminal 80 side is used.
L (Uniform Resource Locato
r) to the WWW server 90.

[0005] The WWW server 90 determines whether the URL received by the http program 91 is a CGI script, and if the URL is a CGI script, activates the CGI program 92. The CGI program 92 writes the execution result to the standard output, and the http program 91 returns the result to the WWW browser 81 on the terminal 80 side, and the WWW browser 81 displays the result.

[0006] As described above, since the program is executed on the server each time it is accessed by using the CGI in the HTML file to be browsed, the program is dynamically executed according to the information sent from the user and the state of execution. Although it is possible to create pages that change rapidly, the dependence on server machines is increasing. Therefore, a method has been considered in which an http server is provided in the terminal, and various processes are easily realized by incorporating a program module for executing a CGI script or the like into the http server of the terminal in the form of a function.
