Abstract
An Internet service provider includes a cache server and a network aware server. The network aware server is operable to determine an optimization between a cost of retrieving content from a network and a cost of caching content from the network at the first cache server and then send a content identifier to the cache server. The cache server is operable to receive the content identifier, and determine the source of a content item. If the source is the same as the content identifier, then the cache server caches the content item.
