Sessions with register_globals = off

Hello, I'm working with register_globals turned off. I'm setting this session cookie: if ($nresult) { if (mysql_numrows($nresult)) { session_start(); $_SESSION['auth'] = 'TRUE'; } } And then I'm checking if the cookie is set, but it doesn't work: if ($_SESSION['auth'] == 'TRUE') { show_menu(); } Is there any error on my code ? What am I doing wrong ? I read this on http://www.php.net/release_4_1_0.php: "Another neat trick is that creating new entries in the $_SESSION array will automatically register them as session variables, as if you called session_register(). This trick is limited to the session module only - for example, setting new entries in $_ENV will *not* perform an implicit putenv()." That's what I am not using sessione_register($variable).
