If you won't enable trans_sid, you'll only have cookie based session, so
on each page you can test for cookie presence in $HTTP_COOKIE_VARS global
array, or, if you have register_globals on (practice for newbies), in
$GLOBALS.
So, you'll supposedly have an "entrance" page:
[index.php]
<?php
setCookie('haveCookies',1);
Header('Location: http://site/main.php');
?>
[main.php]
<?php
if (empty($HTTP_COOKIE_VARS['haveCookies'])) {
return include "error.php";
}
// the rest of php code goes here.
?>
And BTW of globals off, ppl complain it's a lot to type (yap, one of
the virtues of a programmer, laziness), but hey you can assign those
long-named arrays to something simple, so if you have to work a lot
with, say, GET vars, just say $GV = $HTTP_GET_VARS; and go ahead w/ $GV.
ciao
