The various scopes available to a CFCoder have different visibilities and
lifetimes. A request variable has a lifetime of the request that it was
created in. When a user requests a page, and Application.cfm begins
processing, no request variables exist, so IsDefined("request.x") in an
application.cfm will also show that the variable does not exist if you
haven't yet set it anywhere.
As soon as the page finishes processing any request variables are destroyed.
So if you are setting them in your application.cfm just set them, and don't
worry about the IsDefined check in this case.
