Abstract
Disclosed is a program for pre-fetching resources. A computer, communicatively coupled to a plurality of client computers and a server computer, identifies a resource, through an examination of one or more HTTP server logs, that is cached on at least one of the plurality of client computers and has been validated by the server computer. The computer determines to pre-fetch the resource based on one or more predefined rules, at least one of the predefined rules including a threshold number of responses validating the resource that must be received by the computer. The computer pre-fetches and caches the resource from the server computer. The computer receives a request for the resource from a client computer that does not have the resource cached. The computer validates resource cached locally and sends the resource to the client computer from the local cache on the computer.
