Unsetting Sessions

[golfinggod]

Hi can anyone see a problem here this code isnt unsetting these session variables

session_start();  

unset (	$HTTP_SESSION_VARS['username'] );
unset (	$HTTP_SESSION_VARS['password'] );
unset (	$HTTP_SESSION_VARS['date'] );
unset ( $HTTP_SESSION_VARS['time'] );

header("Location: Index.php"); 

On a second page I have this code

if (isset ($HTTP_SESSION_VARS['username']))
{

   header("Location: Index3.php"); 

}  

The problem is every time try to unset the code and the test it by going to the second page, it continues to redirect me.

if those are all of your session variables, try a session_destroy() instead.
