Abstract: A method and system for dynamic distributed data caching is presented. The system includes one or more peer members and a master member. The master member and the one or more peer members form cache community for data storage. The master member is operable to select one of the one or more peer members to become a new master member. The master member is operable to update a peer list for the cache community by removing itself from the peer list. The master member is operable to send a nominate master message and an updated peer list to a peer member selected by the master member to become the new master member.

Abstract: A cache server (18) may prefetch one or more web pages (30) from an origin server (16) prior to those web pages being requested by a user (13). The cache server determines which web pages to prefetch based on a graph (42) associated with a prefetch module (40) associated with the cache server. The graph represents all or a portion of the web pages at the origin server using one or more nodes (130) and one or more links (100) connecting the nodes. Each link has an associated transaction weight (102) and user weight (104). The transaction weight represents the importance of the link and associated web page to the origin server and may be used to control the prefetching of web pages by the cache server. The user weight may be used to change a priority (46) associated with a request (22) for a web page. The user weight and transaction weight may change based on criteria (50) associated with the origin server.

Abstract: A method and system for dynamic distributed data caching includes providing a cache community of peer members and a master member. A master member volunteers to leave the cache community upon which decision a peer member is selected to become the new master member. Each peer member 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.

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.

Abstract: A web browser (20) at a client (12) generates a request (26) for content from an origin server (18). A cache server (16) intercepts the request and examines the request to determine whether the request should be transformed. More specifically, the cache server compares transform criteria (40) to a uniform resource identifier portion (28) and a header portion (30) associated with the request. By transforming the request such that information in the header portion is included in the uniform resource identifier portion, the cache server can cache the content associated with the request using the uniform resource identifier portion of the request.

Abstract: A data center (14) receives a request (22) for content from a browser (12) on a client (11). The data center determines whether the requested content is available at the data center. The content is available when the content is both present at the data center and current. The content may be expired and marked as non-available in response to an expiration command (24). When the requested content is available at the data center, the data center returns the requested content to the data center. When the requested content is locally unavailable at the data center, the requested content is retrieved from an origin server (18). The retrieval of the content from the origin server may be delayed based on the processing load at the origin server. When retrieval of the content is delayed, the request is prioritized and placed in a queue for handling by the origin server based on the priority of the request.
