Abstract
Embodiments disclosed herein provide a high performance content delivery system in which versions of content are cached for servicing web site requests containing the same uniform resource locator (URL). When a page is cached, certain metadata is also stored along with the page. That metadata includes a description of what extra attributes, if any, must be consulted to determine what version of content to serve in response to a request. When a request is fielded, a cache reader consults this metadata at a primary cache address, then extracts the values of attributes, if any are specified, and uses them in conjunction with the URL to search for an appropriate response at a secondary cache address. These attributes may include HTTP request headers, cookies, query string, and session variables. If no entry exists at the secondary address, the request is forwarded to a page generator at the back-end.
