Your understanding is correct, Matt, but I don't see how your
example is relevant.
In my application.cfc, I've got a line that sets an application variable:
<cfset application.siteShortDomain = "myShortDomain.com">
I need that application.siteShortdomain variable available when contact.cfc
runs.
So, how would I go about this?
(I just noticed what Brian and Russ added to the conversation,
and Russ is correct, as you can see from above, that I want to extend
the global application variables that I've set in application.cfc tp all
the other cfc's that are in a common library of cfc's above the website
root.
???
Thanks!
Rick
