I'm not sure. I understood that for such variables you should use <cfparam>,
but I guess in reality there would probably be little or no performance gain
unless you were using it alot.

So would <cfparam> be cheaper than just doing a <cfset> anyway - say for an
Application variable whose value is constant?

Yup, CFPARAMs in your application.cfm file will 'set' empty variables, which
you can fill later.
That way, you don't need to check for their existence, just see what they
are.

This doesn't answer your question directly, but if you are really going to
test for the existence of a variable, and create it if it doesn't exist, I'd
suggest using <cfparam> which will accomplish both of those things in one
step. I only used IsDefined if I want to check for the existence of a
variable, and I'm NOT going to create it if it doesn't exist.

Anyone have any idea whether an IsDefined('') 'costs' more than a <cfset>?
i.e. Which is more work for the server - to test for the existence of a
variable (and create it if it doesn't exist) or create or overwrite it
anyhow?
Thanks.
