Abstract
A communication manager for web-based applications 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, the communication manager may receive messages identifying terminal activity at one of the applications and may signal to the other applications to keep their sessions active.
