Abstract
A method and apparatus for dispatching document requests in a proxy to more efficiently allocate the document cache space within the proxy is provided. A proxy includes a document cache storing recently requested documents. The proxy is coupled to a client and to a remote server. A Uniform Resource Locator (“URL”) is included in the document request. The proxy forwards the request to one of a plurality of proxy servers based upon the URL. According to another aspect of the present invention, the proxy performs a hash function on the URL that maps the URL to exactly one of the plurality of proxy servers. Advantageously, in this manner, mutually exclusive portions of the Web's content can be allocated to particular proxy servers.
