When you set a cookie, its value is not immediatly available in the script. You must redirect the script to another. The the cookie value will be useable.

From the manual:

Cookies will not become visible until the next loading of a page that the cookie should be visible for.

In other words, you can't access a cookie in $HTTP_COOKIE_VARS if you have set it 3 lines ago.

Check out the manual for more info about cookies.
