Abstract: A method, system, and computer program product for exchanging supplemental information fields between a client and server. This supplemental information can then be used by the server to complete a client's request for content stored at a particular location. For example, the supplemental information may be used to provide a customized response, or for access control to sensitive data. Preferably, the REDIRECT message of the Hypertext Transfer Protocol (HTTP) or the Wireless Session Protocol (WSP) is used to request the supplemental information, encoding a comma-separated list of attribute names in a request header for the desired supplemental information. This solution is designed to be backward-compatible.

Abstract: A method for exchanging one or more supplemental fields between a client and a server comprises receiving a client request 405 for a URL, and determining whether the server can complete the request 410. If the server cannot complete the request but another server can, a Redirect message 435 is returned to the client specifying a different URL associated with a different server. A supplemental information request 437 is sent to the client if any of the supplemental information fields are required before completing the client request. If a predetermined number of events to obtain the supplemental field are unsuccessful, or if no server can complete the request, an error message 425 is returned to the client.
