Yep this is because CGI vars come from the web server, and CF will poll the server for any Cgi variables it doesn't "know" about. When you dump the CGI scope you're only seeing ones CF knows should exist, not necessarily the ones that do.
For instance, on Apache you can access system environment variables using the CGI scope - CGI.systemroot on windows, for example. Requesting one that truly doesn't exist will just return an empty string, as people have noticed :) ~k -----Original Message----- From: Rick Root [mailto:[EMAIL PROTECTED] Sent: Friday, February 10, 2006 8:41 AM To: CF-Talk Subject: Re: Invalid CGI variables not generating errors so I guess all those instances where I verify the existence of a CGI variable are pointless!
