| Abstract: |
A method and apparatus provide improved cache coherency and more effective caching operations without placing an undue burden on network links. A proxy receives a request for a resource and then, depending on information in the proxy cache, generates a resource request for transmission to a resource server. The proxy appends a proxy filter to the request. The resource server maintains one or more volumes of resources based on some predetermined criterion that can be either static or dynamic in nature. Upon receipt of the request and the proxy filter the resource server generates a request response and a piggybacked list of additional resources selected from the volume with which the requested resource is associated.

What is claimed is:
1. A method for effecting a transfer of information to a proxy server, the method comprising the steps of:
- receiving a request for information regarding a resource;
- generating a response to said request, said step of generating including the substeps of,
- retrieving the requested information,
- reviewing, volume information correlated to the resource,
- determining a set of additional information to be related to said resource including the substeps of,
- analyzing the received request to identify the resource associated with request and to interpret a filter related to a proxy that sent the received request;
- identifying, based on the output of the analyzing step, at least one further resource related to said resource including the substeps of:
- reviewing volume information correlated to the resource associated with the request; and
- creating a set of further resources based on said review and the interpretation of the filter, and
- compiling information about any identified further resource, and combining the retrieved information and the set of additional information; and
- transmitting said response to the proxy server.
