Cookie Redirection
 

For something seemingly simple, this has been giving me a headache. Let me describe what I'm trying to achieve here: I've setup an Intro. Page at "mysite.com/intro", our forums are located at "mysite.com/forum" -- now, what I want to do is have a link on the Intro. Page where the user can select to not be taken to this page anymore, via cookies. So what I'm trying to do is have "mysite.com/index.php" check if the user has this cookie and if so redirect them to the forum, however, if the user doesn't have this cookie it redirects them to the Intro. Page.

Like I said, seems simple - but I can't for the life of me get it to work properly. I can get the user redirected to the forum when visiting the Intro. Page if they've got the cookie, but for some reason even though the Cookie is set, the "mysite.com/index.php" page is saying that it doesn't exist and redirects to the Intro. Page.

If anyone has an idea of where I'm going wrong here, please jump in.
