Abstract

A cache control method is provided which allows a cache state in a proxy server and a client use state to be synchronized and can improve a cache-efficiency regardless of time zones. A cache control method of a proxy server for relaying data between one or more clients connected to one communication network and a data server connected to the other communication network with a white list, includes the steps of determining whether or not a URL requested by a user of the client is registered in a white list, and processing data at the URL to be cached if the URL is registered in the white list.

Claims

1. A cache control method of a proxy server for relaying data between one or more clients to one communication network and a data server connected to the other communication network with a white list, comprising the steps of:

determining whether or not a URL requested by a user of the client is registered in a white list; and

processing data at the URL to be cached if the URL is registered in the white list.

2. A cache control method of a proxy server with a white list according to claim 1, wherein the white list is a list in which a useful URL used by the user or members of a specific group frequently is registered or a list registered and managed by specific software for a special purpose;

and the white list includes one or both of a list managed by a Web browser and the list managed by specific software for a special purpose.

3. A cache control method of a proxy server with a white list according to claim 1, further comprising the steps of, for controlling the data caching:

providing the white list in the client;

performing the determination by the client;

setting and sending a cache ID indicating whether the data needs to be cached or not by the client in the HTTP request; and

identifying whether the data is to be cached or not based on the cache ID set in the HTTP request.

4. A cache control method of a proxy server with a white list according to claim 1, further comprising the steps of, for controlling the data caching:

storing the white list in a memory medium in the proxy server and then performing the determination by the proxy server.

5. A cache control method of a proxy server with a white list according to claim 1, wherein the communication network to which the clients are connected is a LAN or an intranet to which the data server is connected;

and the communication network to which the data server is connected is a LAN, an intranet or the Internet.
