Abstract: A method and system for dynamic distributed data caching is presented. The method includes providing a cache community (402) comprising at least one peer (413). Each peer has an associated first content portion (511) indicating content to be cached by the respective peer. A client (404) may be allowed to join the cache community. A peer list (426) 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 (511) is associated with each peer based on the addition of the client.

Abstract: A cache module (26) at a client computer (12) controls a cache portion (28) on a storage device (24). The cache module communicates with other cache modules at other clients to form a cache community (15). The cache modules store World Wide Web or other content in the cache portions for retrieval in response to requests (32) for content from browsers (30) in the cache community. When the requested content is not available in the cache community, the requested content may be retrieved from an origin server (19) using the Internet.
