Abstract

Mechanisms for prefetching without requiring parsing of a Web page. References to associated images, sound, video, and executable files and hyperlinked Web pages are included in the header portion of the network message used to deliver the Web page. The associated resources may include properly identified resources (e.g., images and sounds) that are to be rendered with the image, or which are known to have a high probability (if not a certainty) of being selected. The associated resources may also included other resources (e.g., hyperlinked Web pages) that have a lesser probability of being selected and which are only retrieved when there is a detected period of browser idle time. That period of idle time is selected such that it is less likely that the user is going to issue an express request for another Web page during a prefetching operation.
