Abstract
To improve the efficiency of media delivery over the Internet, a system and a method are provided for caching remote media files and retrieving cached media files, comprising hardware and software modules as well as steps for storing a remote media file into the cache and retrieving the cached media file based on a signature created by hashing only discrete parts of the media file. The signature is a key for finding the cached media files in the cache upon subsequent requests for the same media file, even if it is received from a different internet location. Media files may be adapted to the characteristics of different media clients, and adapted media files may be equally cached.
