$rand=rand(1,9);
$session_id=$rand.substr(md5($REMOTE_ADDR), 0, 11+$rand);
$session_id.=substr(md5(rand(1,1000000)), rand(1,32-$rand), 21-$rand);
session_id($session_id);
session_start();

$_SESSION['sessionid'] = $session_id;

What I need is some simple way to prevent this from being called more 
than once until they leave the site.  I'm considering the hidden field 
thing but wonder if that is more complex than needed.
