• isCloseIdleSessions

  boolean isCloseIdleSessions()

  Returns whether a session should be closed when all its open UIs have been idle for longer than its configured maximum inactivity time.

  A UI is idle if it is open on the client side but has no activity other than heartbeat requests. If isCloseIdleSessions() == false, heartbeat requests cause the session to stay open for as long as there are open UIs on the client side. If it is true, the session is eventually closed if the open UIs do not have any user interaction.

  Returns:

  True if UIs and sessions receiving only heartbeat requests are eventually closed; false if heartbeat requests extend UI and session lifetime indefinitely.
