<p>PROBLEM TO BE SOLVED: To provide a cache server capable of reducing a load of a communication access network. SOLUTION: In this cache server for caching an object down-loaded from a server to a client terminal through an access network of a communication system in a temporary storage region, or caching an object up-loaded from the client terminal to the server in the temporary storage region, it is predicted by using an evaluation function whether the object up-loaded from the client terminal to the server is down-loaded to another client terminal or not. When the possibility of being down-loaded is low based on the prediction result, the object is not cached in the temporary storage region of the cache server but up-loaded to the server, and when the possibility of being down-loaded is high, the object is cached in the temporary storage region of the cache server and simultaneously up-loaded to the server.</p> |
