The variable FORM.FIELDNAMES doesn't come from the browser; it's created by CF in any script to which form data has been submitted. It's been around in CF since at least version 2, and it allows the construction of generalized form data handlers, since you can loop through the list of all form data sent from the browser with it. Of course, in version 4.x and up, you're probably better off looping over the Form structure. I suspect that FORM.FIELDNAMES has been kept around with its behavior unchanged just for backward compatibility. One interesting thing about FORM.FIELDNAMES is that, if you have multiple form fields with the same name, the name is listed multiple times in FORM.FIELDNAMES, which reflects how the browser actually sends the data. So, if you use it to write a generalized form data handler, you have to take that into account.

Feature.
