Abstract:
1. A method of forwarding requests for content from a client over a network, comprising: (a) receiving a request for content over the network and based on a determination of content generation information included within the request, determining if the requested content is dynamic or static; (b) if the requested content is determined to be dynamic, forwarding the request over the network to a content server that enables access to the dynamic content; and (c) if the requested content is determined to be static, forwarding the request over the network to a plurality of caches that enable access to the static content, wherein the plurality of caches include at least one hot cache, wherein the plurality of caches is organized in a hierarchy and wherein a higher level cache in the hierarchy is associated with a higher frequency of requests for static content than a lower frequency of requests for static content associated with a lower level cache, and wherein forwarding the request over the network to the plurality of caches that enable access to the static content further comprises recursively forwarding requests, generated from different caches in the hierarchy based on the received request and receipt of one of the recursively forwarded requests at each of the different caches in the hierarchy, through the hierarchy until a frequency of the request for static content exceeds a threshold associated with the hot cache and particular to a content set that includes the requested content.
