I've had this problem for years, but have never been able to figure it out. I
often pass session information via the URL. On our local development server,
when I sometimes forget to include #session.urltoken#, the browser keeps on
going as if nothing's wrong. Somehow it does not lose session and thus I don't
realize the error. This happens across multiple versions of CF (6 and 7),
across multiple browsers. This is a problem because when I upload the pages
to the client's site, it always loses session in these places and I have to go
back and fix them. It would be nice if the local system would always lose
session when it's supposed to?

The only thing I can think of is that it may be related to having multiple
sites on the same development server, some of which may be setting session
cookies, while others don't. But they're all running under separate
<cfapplication> tags, and so should have distinct session information? Does
anyone know what could cause this?
