Web pages are prefetched upon activation of one of three server-side triggers: a service trigger, an access based trigger, and a timed trigger. The service trigger is a subscription service in which the web server agrees to notify the proxy when webpages in the web server are modified. The access based trigger uses logs/metrics to analyze a plurality of users' browsing habits. When the log/metrics database noticeS that a particular webpage experiences heavy requesting traffic during a particular time period, the log/metric creates an access based trigger to prefetch the requested webpage. The timed trigger is a prefetching mechanism that occurs on a regular interval. Configuration data instructs the timed trigger to prefetch a certain webpage a certain times throughout the day.
