An easy solution would be to use <cfparam> to initialize variables to a default value
if they don't exist.
You could use something like this:
<cfparam name = "myvar" default = "">
then do a check:
<cfif not(len(myvar))>
<cflocation url="myurl.cfm">
</cfif>
I think it's a little cleaner than using IsDefined and then checking if the var is
empty.
