Abstract

A method for predictive prefetching of objects over a computer network including the steps of providing a client computer system, providing a server computer system, the server computer system having a memory, a network link to the client computer system, the network link also providing connection of the server computer system to the computer network, requesting from the server computer system by the client computer system a retrieval of a plurality of objects, retrieving the plurality of objects by the server system, storing the retrieval and an identity of the client computer system in the memory of the server computer system, sending the plurality of objects from the server computer system to the client computer system over the network link, predicting in the server computer system a plurality of subsequent retrieval requests from the client computer system according to a predetermined criteria, sending the prediction to the client computer system, and prefetching by the client computer system an object based on the prediction and other information. With such an arrangement, an object may be prefetched before a user actually requests it. This makes the retrieval latency appear to be zero when a user requests a prefetched object.
