Abstract
A digital computer network includes a network-infrastructure cache that provides proxy services to a plurality of client workstations concurrently requesting access to data stored on a server. A network interconnecting the workstations and the server carries requests for data to the server, and responses thereto back to requesting client workstations. The network-infrastructure cache receives and responds to requests from the client workstations for access to data for which the network-infrastructure cache provides proxy services. A cache in the network-infrastructure cache stores data for inclusion in responses. If the cache lacks data needed for a response, then the network-infrastructure cache forwards a request for the missing data onto the server, and receives data responsive thereto. In one embodiment the network-infrastructure cache converts requests received from clients in a first protocol into requests in a second protocol for transmission to the server, and conversely.
