A Multicollaborative Push-Caching HTTP Protocol for the WWW

We propose a caching protocol designed to automatically mirror heavily accessed WWW pages in a distributed and temporal fashion. The proposed caching mechanism differs from proxy type mechanisms in that it caches according to load pattern at the server side, instead of access patterns at the client-side LAN, in a Demand-based Document Dissemination (DDD) system fashion. This type of server initiated caching scheme has been termed push-caching. As well, the proposed caching scheme incorporates topological caching functions. The proposed protocol is orthogonal to other extensions to the HTTP protocol and other caching schemes already in use.
