Abstract
Storing content of a particular type at one or more cache servers may be accomplished according to a cache protocol selected according to the type of the content, a site (e.g., an origin server) associated with the content and/or a class of service requirement. In this scheme, the cache protocol may be selected and/or varied according to load balancing requirements and/or traffic conditions within a network. For example, the cache protocol may migrate from a first protocol (e.g., CARP) that allows only one copy of the content to be stored to a second protocol (e.g., HTCP or ICP) that allows more than one copy of the content to be stored. Further, the depth to which a request query is to be searched within a cache hierarchy may be determined according to the site, the content type and/or the class of service. Where necessary, a path for retrieving the content may be determined, at least in part, according to the content type.
