I would use a cfif isdefined block to check if they've been set
and if not then do the include. There's no reason to keep resetting
them. There is no danger of a race condition unless 2 users
could be trying to set them to different values.
There's a big difference between this and using local vars
though. With local vars each user would be recreating a new
copy for each .cfm template loaded, whereas with application
vars they all share the same one.
