CF, being a high-level language, has its own garbage collection, so you don't have to worry about this kind of stuff. It's just as good to overwrite a variable as it is to delete it and recreate it - even better, from a performance point of view. However, it's worth pointing out that in your first example, you have: <cfset session = StructNew()> You'll want to be careful with that. CF creates a few session variables, and can get confused if you delete them. I'd recommend just deleting the variables that you've created.
