In order to use session variables, CF has to keep track of who is whom. Therefore, it sets two cookies without you knowing it (assuming you've enabled session or client variables): CFID and CFTOKEN. Therefore, if you don't want to use cookies, you have to explicitly disable them in the CFAPPLICATION tag.
For more information, check out the Client Variables section of the Developing Web Applications with ColdFusion book (part of the documentation, online if you don't have a hardcopy). There are ways to do session/client tracking without cookies, but you have to manually pass the CFID/CFTOKEN combo in URLs or forms between pages. If you forget even one link or form, the session dies and the user gets a new one. I'm sure there are MANY great presentations floating around with more details on how to do this. If you can't find one, I've got one stashed away someplace.

All you need to do is setup a datasource in the ColdFusion Administrator and set it as the default storage mechanism for client variables. CF takes ca re of the rest. ----- Original Message ----- From: "Norman Elton" <[EMAIL PROTECTED]> To: "CF-Talk" <[EMAIL PROTECTED]> Sent: Monday, January 28, 2002 12:50 PM Subject: RE: CF and Hit Counter > So long as you realize that session variables typically rely on > cookies (you'd have to use the SetClientCookies=no attribute of > CFApplication - > I believe that's what it's called).
