Description:
------------
When forcing PHP to not use cookies for sessions, PHP doesn't recognize the existing session. Instead it will create a new one. Session files will be created as expected.

The Bug can be reproduced with:
1.) ini_set('session.use_cookies', 0); in the php-code
and
2.) session.use_cookies = 0; in php.ini

The following sample code is identical to http://www.php.net/manual/en/session.idpassing.php

Reproduce code:
---------------
<?php
// Disable Cookie-Usage
ini_set('session.use_cookies', 0);

// Start the session
session_start();

if (empty($_SESSION['count'])) {
	$_SESSION['count'] = 1;
} else {
	$_SESSION['count']++;
}
?>

<p>Hello visitor, you have seen this page <?php echo $_SESSION['count']; ?> times.</p>
<p>To continue, <a href="test.php?<?php echo htmlspecialchars(SID); ?>">click here</a>.</p>

Expected result:
----------------
On the first run, a new session should be created with $_SESSION['count'] = 1. On everey reload $_SESSION['count'] should be increased. (s.a. example #1 at http://www.php.net/manual/en/session.idpassing.php)

Actual result:
--------------
On every run, PHP creates a new session with $_SESSION['count']=1.
