1. A method comprising: caching, in a network caching device on a network, objects that originate from a plurality of origin servers; receiving at the network caching device requests for various ones of the objects from a plurality of clients; and using a translation mechanism in the network caching device to service the requests, the translation mechanism establishing a layer of indirection between client-side handles used by the clients to request the objects and server-side handles corresponding to said objects, wherein using the translation mechanism includes using a file handle mapping in the network caching device to translate a client-side file handle to a server-side file handle used by an origin server that stores an object, the mapping being based on a hash which is a function of an address of the origin server and at least a portion of the server-side file handle.
