Abstract
In a communication arrangement including a multiplicity of intranets, objects available on the Internet are requested. A requested object in an intranet is attended by a proxy server therein, which attempts to locate a copy of the requested object in a proxy cache. The latter stores copies of objects previously obtained by web browsers in the intranet, and affords priority to copies of those objects from selected Internet sites. If the proxy server does not manage to locate a copy of the requested object or determines that a located copy is outdated, the proxy server seeks cooperation from other proxy servers to further search for the object. These cooperating proxy servers are dynamically identified by a manager processor in accordance with the invention. In addition, the manager processor prefetches selected objects from the Internet in anticipation of the object request. The manager processor also helps search the prefetched objects for the requested object.
