[TYPO3-english] Clear FE user session data on logoff

[Victor Livakovsky]

Hi, list.

I wonder, if there is a way to instruct the core to remove session data of 
current FE user, when he logs of?
I'm intensively using at one of the webs: 
$GLOBALS['TSFE']->fe_user->setKey('ses', $name, $data); and that data stays 
in a session even, if user logs out. So, if another user logs in (without 
closing browser, which kills a whole session), he may see some temporary 
stuff, related to previously logged in user. Can this somehow be avoided?

Thank you in advance.
