[Chameleon] Problem with destroying session

[Yahya Mohammad]

Hi 
I've added login and logout pages to my Chameleon application using 
Chameleon's session handling. On logout I call session_destroy which calls a 
_destroy() function in htdocs/common/session/session.php but it doesn't seem 
to do anything. I'm running Chameleon on Linux.

There's a block of code in that function which looks like it actually deletes 
some session files but it's  commented out for some reason. Can anyone 
explain to me how Chameleons session destruction works?

Thanks in advance.
Yahya
