I wont start on the frames (yuk)
But a simple way could be to log each frames current URL in a unique
SESSION variable when each request is made.
something like...
$_SESSION['frame_url']['parent'] = '
http://something';
$_SESSION['frame_url']['left_side'] = '
http://somethingelse';
$_SESSION['frame_url']['main_body'] = '
http://anotherplace';
It isnt pretty but it might help you out.
I would lose the frames (uggggh) it isnt 1997 anymore.
