Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an arrangement of HTML content on a server and a server program such as a CGI (Common Gateway Interface) and an access method thereof when accessing a homepage or the like using WWW (World Wide Web) on the Internet. In particular, the present invention relates to a WWW server distributed access method suitable for use in distributing server load when a large amount of contents utilizing a large number of server programs such as CGI are created.
[0002]
[Prior art]
A general data communication operation using HTTP (Hyper Text Transfer Protocol) in the WWW is performed by requesting HTML content from a WWW server from an HTML (Hyper Text Markup Language) content browsing program called a WWW browser on a client side. Transmits HTML content in response to a request from a client, the client receives the HTML content transmitted from a WWW server, shapes the information received by a WWW browser, and displays the information on a display. is there.
[0003]
However, the HTML content described above is static information, and the information transmitted to the client does not change unless the content arranged on the WWW server is changed, and two-way data communication is impossible.
[0004]
As a conventional technique for solving such a problem, a program such as a CGI is arranged on a WWW server, and the program is operated on the server in response to a content request from the client. A method for realizing a reliable data communication is known. In recent years, a technique of transmitting a program to a WWW browser on a client side and processing the program by using a technique such as Java (registered trademark) has also been standardized.
[0005]
[Problems to be solved by the invention]
However, according to the above-described conventional technology, since programs such as CGI are usually arranged on a WWW server on which HTML content is arranged, a heavy load is imposed on the server when access is concentrated on the WWW server. There is a problem that it becomes a major factor that lowers the processing capacity of the server.
[0006]
In recent years, an Internet user who does not have a WWW server has been actively publishing a homepage using the WWW by borrowing a function of the WWW server and a data storage area. In this case, when using the CGI program together with the HTML content, it may be necessary to write a program code depending on the borrowed WWW server. Furthermore, writing the program code itself requires appropriate skills. This fact means that it makes it very difficult for a person with little computer knowledge to create a homepage as described above.
[0007]
SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described problems of the prior art, and to enable a server that distributes HTML content and a server that processes a server program such as CGI and distributes the result to be distributed and arranged. It is an object of the present invention to provide a WWW server distributed access method capable of reducing the traffic of the Internet.
[0008]
Another object of the present invention is to provide a WWW server distributed access method which enables even a person who has difficulty creating a program to easily create a homepage utilizing a server program such as a CGI without writing a CGI script at all. Is to do.
[0009]
[Means for Solving the Problems]
The object according to the present invention is a W WW server distributed access scheme that put the system configured by connecting a WWW server and a WWW client via a network, the WWW server, HTML server for distributing HTML content And a CGI server that executes a CGI program, wherein the HTML server, in response to a web page request from a WWW client, stores HTML content including an identifier that identifies the CGI server to execute and the CGI program. Means for distributing to a WWW client, wherein the CGI server receives a request for starting a CGI program from the WWW client based on the HTML content distributed from the HTML server, executes the corresponding CGI program, and executes the CGI program This is achieved by providing means for delivering results to the WWW client .
[0010]
In addition, the objective is, in the HTML description file of the HTML content, script to start the CGI program on the CG I servers is more accomplished in that you have written.
[0011]
In the above description, when the WWW client accesses the content on the HTML server, the WWW client accesses the corresponding CGI server existing on a CGI server different from the HTML server and starts the program. The CGI server transmits the processing result to the WWW client, and the WWW client fuses the linked HTML content and the processing result information, and displays the fused information on a display using a WWW browser.
[0012]
As described above, according to the present invention, it is possible to distribute a server that distributes HTML content and a server that processes a server program such as CGI and distributes a result, thereby reducing traffic to a WWW server. In addition, by centrally managing a program such as a CGI on a server and providing it as various components, even a person who has difficulty creating a program can easily create a homepage utilizing a server program such as a CGI.
[0013]
