The popularity of the Internet has produced an increased demand on performance and functionality in the form of Web-applications. A Web-application is a collection of logically related hyperlink Web pages that provide a specific service to Web clients. The combination of a hyperlink predictor in conjunction with Web-applications has the potential to reduce the loading time of Web-application pages. We propose a Web-application centric object prefetcher that augments the customary demand-fetching mechanism founded in most Web browsers utilized for object caching. This technique is complimentary to the operations of Web browser and proxy server caching. It predicts Web-application users' click actions in order to launch requests for future Web page objects, such that they are available at the client's system when they are needed. We have conducted trace-driven simulations that indicate the possible performance gains associated with Web-application centric prefetching, when combining demand fetching and prefetching within a Web-application's bounded hyperlink domain. © 2002 Elsevier Inc.
