Method and apparatus for improving end to end performance of a data network
First Claim
1. A method for effectuating a transfer of information to a proxy server, the method comprising the steps of:
- receiving at a resource server a request for information regarding a first resource;
generating at said resource server a response to said request, said step of generating including the substeps of;
retrieving the requested information, identifying at least one further resource related to said first resource, said substep of identifying at least one further resource includes the substeps of;
identifying a filter related to a proxy that sent the received request, and identifying, based on the output of the interpreting step, at least one further resource related to said first resource, compiling additional information which relates to said identified further resource, and combining the retrieved information and the additional information; and
transmitting said response to the proxy server.

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.

5. A device-readable medium storing program instructions for performing a method of operating a resource server and effectuating a transfer of information to a proxy server, the method comprising the steps of:
-
receiving at the resource server a request for information regarding a first resource;
generating at said resource server a response to said request, said step of generating including the substeps of;
retrieving the requested information, identifying at least one further resource related to said first resource, said substep of identifying at least one further resource includes the substeps of;
interpreting a filter related to a proxy that sent the received request, and identifying, based on the output of the interpreting step, at least one further resource related to said first resource, compiling additional information which relates to said identified further resource, and combining the retrieved information and the additional information; and

9. A device-readable medium storing program instructions for performing a method of operating a resource server and effectuating 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. - View Dependent Claims (10, 11, 12)
