Abstract
A system and method of automatic session resource clean-up resulting from a client-server session wherein the client has requested use of server resources during the session. During each session, a list of the resources allocated to that session and associated with the client is maintained and, when the session terminates, either naturally or unnaturally, the allocated resources are released or freed up, allowing later use of the same resources by a different session, either with the same client or with a different client. Because unnatural terminations do not normally provide a farewell message from the client to the server there is no way for the server to release the resource and no naturally occurring message to the server that the client is not present. The present invention overcomes these disadvantages by determining when a session has ended and releasing the resources associated with the client.
