Abstract

A preloader works in conjunction with a web/app server and optionally a profile server to cache web page content elements or components for faster on-demand and anticipatory dynamic web page delivery. The preloader uses a cache manager to manage requests for retrievals, insertions, and removal of web page components in a component cache. The preloader uses a cache replacement manager to manage the replacement of components in the cache. While the cache replacement manager may utilize any cache replacement policy, a particularly effective replacement policy utilizes predictive information to make replacement decisions. Such a policy uses a profile server, which predicts a user's next content request. The components that can be cached are identified by tagging them within the dynamic scripts that generate them. The preloader caches components that are likely to be accessed next, thus improving a web site's scalability.

Dependent claims

A web page delivery system for dynamically generating a web page having at least one content element, the delivery system comprising:

a web/app server operative to receive a web page request from a user to generate a web page and to deliver the web page to the user, said web/app server further operable to generate a hint request;
a preloader operative to receive a content element retrieval request from the web/app server and to deliver the at least one content element to the web/app server, wherein the preloader is in communication with the web/app server, and wherein the preloader comprises a component cache, local to the web/app server, for maintaining the at least one content element;
and
a profile server operative to receive the hint request from the preloader and to deliver a hint to the preloader;
wherein the preloader delivers the at least one content element to the web/app server in response to a determination that the hint indicates that the at least one content element will be needed by the web/app server to generate the web page, and wherein the at least one content element is provided by the component cache local to the web/app server to reduce the time required to generate the web page.
