1. A method for dynamic distributed data caching, comprising:
- generating a content request for requested content at a first peer in a cache community;
determining a second peer associated with the requested content, the second peer being associated with the cache community; and
retrieving, by the first peer, the requested content from the second peer;
wherein determining the second peer includes;
generating, by a cache portion associated with the first peer, a location request;
communicating the location request to a master associated with the cache community; and
receiving a location response from the master, the location response indicating the second peer.

Abstract
A method and system for dynamic distributed data caching is presented. The method includes providing a cache community comprising at least one peer. Each peer has an associated first content portion indicating content to be cached by the respective peer. A client may be allowed to join the cache community. A peer list associated with the cache community is updated to include the client. The peer list indicates the peers in the cache community. A respective second content portion is associated with each peer based on the addition of the client.

1. A method for dynamic distributed data caching, comprising:
-
generating a content request for requested content at a first peer in a cache community; determining a second peer associated with the requested content, the second peer being associated with the cache community; and retrieving, by the first peer, the requested content from the second peer; wherein determining the second peer includes; generating, by a cache portion associated with the first peer, a location request; communicating the location request to a master associated with the cache community; and receiving a location response from the master, the location response indicating the second peer.

2. The method of claim 1, further comprising:
-
retrieving, by the second peer, the requested content from an origin server when the requested content is unavailable at the second peer; and storing the requested content at the second peer.
-
-
3. The method of claim 2, wherein the requested content is unavailable when the requested content has been expired.
-
4. The method of claim 2, wherein the requested content is unavailable when the requested content is not stored at the second peer.

10. A computer readable storage medium including code for dynamic distributed data caching, the code operable to:
-
generate a content request for requested content at a first peer in a cache community; determine a second peer associated with the requested content, the second peer being associated with the cache community; and retrieve, by the first peer, the requested content from the second peer; wherein the code operable to determine the second peer is further operable to; generate, by a cache portion associated with the first peer, a location request; communicate the location request to a master associated with the cache community ; and receive a location response from the master, the location response indicating the second peer.
