Abstract: A web server that can be flexibly changed may include storage for a session state; a reception unit for receiving the session state while associating it with a primary HTTP request, from a terminal; storage for the received session state which is accessed as an HTTP session object by a processing program for responsive to the received primary HTTP request; a unit for accessing the stored session state responsive to executing an access instruction contained in the processing program; and a return unit for reading the session state from the storage unit responsive to executing an instruction generating an HTTP response contained in the processing program, setting the session state to the primary HTTP response as a parameter to be transmitted by the terminal in association with a secondary HTTP request, and returning the set primary HTTP response to the terminal.
