Abstract: A method, a system, an apparatus, and a computer program product are present ed for fragment caching. After a message is received at a computing device that contains a cache management unit, a fragment in the message body of the message is cached. Subsequent requests for the fragment at the cache management unit result in a cache hit. The cache management unit operates equivalently in support of fragment caching operations without regard to whether the computing device acts as a client, a server, or a hub located throughout the network; in other words, the fragment caching technique is uniform throughout a network. Cache ID rules accompany a fragment from an origin server; the cache ID rules describe a method for forming a unique cac he ID for the fragment such that dynamic content can be cached away from an origin server.

Abstract: Coordinated, hierarchical caching of objects in a client/server system. In the described embodiment, an encapsulated cluster 70 comprises one or more level 1 nodes 20, e.g. Web server accelerators or routers, each including at least one level 1 cache 30, and one or more level 2 nodes 40, e.g. Web servers, within which the objects are permanently stored or generated on request. Each level 2 node is coupled to at least one level 1 node and includes one or more level 2 caches 50. More levels can be included. Object caching is based on various described criteria: for instance, the level 2 cache(s) can be used to cache dynamic pages which are expensive to create, while the level 1 cache(s) can be used to cache static pages, and hot dynamic pages. Different cache replacement policies for the level 1 cache(s) are also described (Fig. 4), in order to optimize performance whether the performance bottleneck is router processing power, server processing power, or the network between the server(s) and the router.
