Hi Evan,
When you use a cfcookie, the server (IIS or whatever you're using) sends an
HTTP header to the client... and then sends your CF page. So, when you set
a cookie and then immediately test for it, ColdFusion thinks it exists
whether or not the browser accepts it. You have to do something like this:
a) set cookie on page a
b) do a redirect (not using cflocation) to page b
c) test for cookie page b
You can test for a cookie on page b because the browser will request page b,
thus sending any cookies it has accepted.
Hope that helps. If not, you might want to dig into some discussions of
cookies (http://www.netscape.com/newsref/std/cookie_spec.html) and HTTP
headers.
