ABSTRACT:
The present invention aims to embody a cache server which can provide the service of the same quality as a media server. A client sends a delivery request for a streaming delivery of a specific media file to a media server, and a cache checking unit of the cache server checks if the requested media file is stored in a cache file storing unit as a cache file. If it is stored, a file streaming delivering unit performs the streaming delivery to the client using the cache file. If not stored, the cache checking unit transfers the delivery request to the media server, and the media server performs the streaming delivery, and in parallel with the streaming delivery, at the cache server, a media file obtaining unit obtains the requested media file from the media server and stores the requested media file in the cache file storing unit.
