US Patent 7548947 Predictive pre-download of a network object

A method for enabling pre-downloading of network objects to a web client from a web server is described. The method includes intercepting at a device a request from a web client to a web server for a first network object. The same device intercepts a response to the request from the web server. The device determines a second network object most probable to be requested in the future from the web server. Subsequently, a message is sent from the device to the web client the first message informing the web client of the second network object to be cached by the web client. A second message is sent from the web client requesting the second network object. The second network object is received and predicatively pre-downloaded into a cache whereby a latency for requesting the second network object is reduced when requested in response to an actual user request.
