sessions handling

I copied global.php and am using that copy for authentication of other pages. How can I remove the string

's=c28dd3b6af30bdc2165a6e730957e19f'

in there? So the page displays as whatever.php instead of whatever.php+that string

Take the

?s=$session[sessionhash]

out of the url

well the session is added to the link, so you have to edit the link to whatever.php to remove the s=....
