SYSTEM AND METHOD FOR OPTIMIZING NAME-RESOLUTION OVERHEAD IN A CACHING NETWORK INTERMEDIARY DEVICE

摘要

The present invention describes a system, method, and article of manufacture for resolving names received in network protocol requests by a network intermediary device coupled between a client network and a server network. A deferred trust model caching engine in the network intermediary device includes a transactor module configured to efficiently process a protocol request with a sequence of determinant criteria, although the sequence can occur in different orders. The deferred trust model caching engine includes a cacheability evaluator component configured to determine whether the protocol request is for a resource that the protocol permits to be cached by the network intermediate device, and a supplier trust evaluator component configured to compare information about the client's network protocol request and a cached object representation to determine if the object is trustworthy or not. The cached object representation associates an object with a supplier identity and a supplier trust property.
