摘要

Implementation method of tracking mechanism in a communications session state between a server and a client system the present invention refers to a method to implement tracking mechanism in a communications session state between a server (1). A client system (2), where, in the course of the session and communications.Application data is provided to the client system (2) in a form accessible only if the client system (2) has a valid value of the tracking information of the state, which includes transmitting a message carrying a new value of the information of tracking state pa To the client system (2).He additionally includes calculating the value of information of tracking valid state after the transmission of the message using as input at least the new value carried in the message and a stored on the client system (2).
