I'm passing the Session ID along from page to page as a means to keep track of the user and identify them. I've noticed that sometimes the Session ID is displayed in the URL (that's how I'm passing it), but sometimes it's not displayed there. Even when it's not displayed, everything still seems to work...I was just wondering if anyone knew why it would only display sometimes. When it doesn't display, I still get pagename.php?, just not the ID after the question mark. Any ideas?
