Abstract: A system is disclosed for storing content received from a data communications network. The system includes at least one physical memory device for implementing a cache memory and a cache memory manager responsive to content received from at least two sources for associating an identifier with content stored in the at least one physical memory device that distinguishes content received from a first source from content received from a second source. The cache memory manager is further responsive to the identifiers for performing at least one cache management function differently for the content received from the first source than for the content received from the second source. In a mobile station embodiment that includes a HTTP browser the invention permits HTTP content received from a wireless network operator to be stored and managed separately from other received HTTP content.
