The purpose of the invention is to provide a distributed cache system applicable to a large-scale network having multiple cache servers. In a distributed cache system including multiple cache control servers, the content information is divided and managed by each cache control server. When content requested from a client is stored in the distributed cache system, a cache cooperation router forwards the content request to the cache control server which manages the information of the requested content. A cache control server has a function to notify its own address to the distributed cache system when the cache control server is added to the distributed cache system. When a cache control server receives the notification, it sends content information to the new cache control server and synchronizes the content information. Thus, a cache control server can be added to the system with ease.
