Clear a variable

I need to display it in the URL because the controller page redirects back to the page they commented with cflocation. Is there another way to do this?

Setting the variable to "" doesn't do me any good because it still considers that as a variable.

I did figure out a solution though.

Why don't you simply not display the comment in the url?

Specializing what Ian says, you would, after displaying the variable, do

<cfset URL.myVariable = "">

or

StructDelete(URL,"myVariable")

OR

StructDelete(scope,"myVariable")
I.E.
StructDelete(variables,"myVariable")
OR
StructDelete(session,"myVariable")
