Even if sessions many times are cookies, they don't use the $_COOKIE
array, but $_SESSION, as you want to be able to access a session the
same way no matter if it's embedded into url or as a cookie.
I suggest you take a look at
http://www.php.net/manual/en/ref.session.php
http://www.php.net/manual/en/function.session-start.php
to see how session works
setcookie() may require you to specify all the arguments, seems to be a
long lived msie bug that makes it to not save a cookie and also keep in
mind that you can't access a cookie value until the script after the one
where you created (the same applies to value changes).
