摘要

PROBLEM TO BE SOLVED: To immediately provide contents such as images and voices when necessary or change the details of the contents according to the processing capacity of a client before communication even when an applet to which an electronic signature is not applied is used. SOLUTION: While the contents are requested from the client, it is judged whether the contents describe a program operated by the client or not. Only when the contents describe the program, the contents are re-written so that an address to be referred to by the program operated by the client becomes the Proxy server, and stored in a cash means. When the program is requested from the client, the program is obtained from the cache means or a contents server by utilizing a cache, and returns the program to the client.
