A system and computer implementable method for updating content on servers coupled to a network. The method includes updating an origin server with a version of files used to provide content, retrieving data that indicates an action to be performed on one or more cache servers in conjunction with updating the origin server, and performing the action to update entries in the one or more cache servers. Each entry in each cache server is associated with a subset of the content on the origin server and may include an expiration field and/or a time to live field. An example of a subset of content to which a cache entry may be associated is a Web page. Cache servers are not required to poll origin servers to determine whether new content is available. Cache servers may be pre-populated using push or pull techniques.
