Session Help

[Anon]

I'm having a problem. I'm creating a session with session_start() and regging a variable with session_register("varname"), and then I use the session in a URL using the <?=SID?>. The session ID appears in the URL the first time, but then when I use the link any times afterwards it doesn't show the session ID, so it doesn't work properly. What could be the problem?

It only shows the session ID in the URL if it has to - i.e., if the browser refused to accept the session ID cookie. If it does, PHP has to store the session ID somewhere else so that it gets returned with each browser request - in the querystring.

<?=SID?> (more accurately, page.html?<?=SID?> is only needed if there's a possibility that browsers of the site won't accept the cookie.

So if the site's not working, and the browser is accepting cookies, then SID's not at fault.
