Abstract
A method and apparatus for providing user specific request redirection in a content delivery network includes parsing a page having embedded objects intended for redirection to at least one cache server, and transforming the embedded objects into relative uniform resource locators (URLs). A content-base token is inserted into an HTTP response header in response to a user request for the page. In an instance where the content-base token is not supported by the server and/or client devices, a base token is inserted into the page in response to a user request for the page. The content-base token and base token provide identification of a server or URL prefix where the embedded objects in the page are to be retrieved. The requested page is then sent to the user's browser. The browser constructs absolute URLs from the embedded URLs using either the received content-base token or base token, to retrieve embedded objects from the server.
