What will happen to session that was not destroyed/unset?
<p>This may seem trivial.</p>

<p>What will happen to a session that was never destroyed/unset/write_close-d?
Lets just say I have set the session to never time out. What will happen to the session if person finds himself at the login page and logs in using different credentials. Also just for the testing purpose, the login page doesn't have redirect if session is set.</p>

<p>Will it overwritten and destroyed or never destroyed?</p>
