If you are like the muse you keep your eye on the log files in the /runtime/logs/ directory. There's some good information in there if you care to poke around. You might notice one item that appears in the *.events.log from time to time - usually in a long list of similar errors. It looks something like:
04/04 07:42:39 error Cannot create cookie: path = /
04/04 07:42:40 error Cannot create cookie: expires = Sun, 28-Mar-2038 12:42:01 GMT
This annoying error has been popping up for years and I have never had a satisfactory explanation for it... until now! Genuine ColdFusion Guru Jochem van Dieten (Europe's answer to Ben Forta) figured out that this comes from cookie requests sent from client to server that are using reserved words like "expires" and "path" in the cookie name.
