  • Communication between client and server computers via http, method, computer program product and system
    Publication number: 20030009562
    Abstract: A client computer (900) and a server computer (901) communicate via HTTP; the client computer (900) uses a standard HTTP-browser (210). Substantially simultaneously with establishing a session by allocating a resource (340) at the server computer (900), the server computer (900) sends a termination instruction (360) to the browser (210) during the whole session. In the event that the server computer (900) terminates the session, such as upon unloading the instruction (360) from the browser (210), the browser (210) causes the server computer (900) to de-allocate the resource (340).
