* its lifetime exceeds x.
* 2. Effect of changing the timeout limit.
* The test suite does not cover the default timeout(24 hours) usage. This
* case has been tested independetly.
*
* Invairant for passing this test is, at any given time,
* lifetime of a session < current_session_timeout, such that
* current_session_timeout > 0, for all sessions cached by the session
