Systems, method and session manager for web-based applications

摘要

A communication manager (220) for web-based applications (230) receives indications of application time outs via a callback mechanism. During session initiation, the communication manager provides a termination address to an application along with a session ID. If the session times out due to inactivity, the application may signal the communication manager that the session ID is invalid by sending a message to the termination address. Alternatively, when a communication manager establishes communication sessions for several applications with a common external terminal (110,210), the communication manager (220) may receive messages identifying terminal activity at one of the applications (230) and may signal to the other applications to keep their sessions active.
