Invalidating the session
Although current session module does not accept empty session ID cookie, but immediate session deletion may result in empty session ID cookie due to client(browser) side race condition.
This will result that the client creates many session ID needlessly.
To use the session variables again, may be used for that. You do not have to remove obsolete session ID cookie because session module will not accept session ID cookie when there is no data associated to the session ID and set new session ID cookie.
