Abstract

A method and system for caching content, such as content requested from a server on the World Wide Web. Requests for dynamic content are forwarded directly to a content server to avoid caching data that might only be used once. Requests for static content are forwarded to a hot or a regular cache depending on the frequency at which the content is requested. When a hot cache does not contain the content, it forwards the request to the forwarder which then forwards the request to a regular cache. When the regular cache does not contain the content, it requests the content from the forwarder which then forwards the request to a content server. There may be more than two layers of cache.
