<p>An external cache (20) for use with a computer network (10) communicates with a client node (18) of the network (10). The external cache (20) contains a number of cached files associated with a network resource (30) such as a Web page. Network files (28) corresponding to the cached files are maintained at a server node (12) of the network (10) and may be downloaded to the client node (18) according to conventional techniques. In response to an end-user request for the Network Resource (30), the computer network (10) searches the server node (12) and the external cache (20) for the associated network files (28) and cached files. Date/time stamps attached to the network files (28) and cached files are processed to determine the most current files associated with the requested network resource (30). The client node (18) retrieves cached files, when such files are current and available, to reduce the access/download time associated with the network resource (30).</p> |
