Abstract: A smart browser working in conjunction with a HTTP server that selectively downloads WWW pages into the browser's memory cache. The determination of which pages to download is a function of a probability weight assigned to each link on a Web page. By evaluating that weight to a predetermined browser criteria, only those pages most probably to be downloaded are stored in the browser's memory cache. The download is done in the background while the browser user is viewing the current Web page on the monitor. This greatly enhances the speed with which the viewer can "cruise" the Web while at the same time conserving system resources by not requiring the system to download all the possible links.
