OK, I know everyone is going to hate me, but I think I can give the most
concise definition of a request variable yet. Think of it as a challenge
in English and efficiency of communication!
Here's my one line definition of request variables:
Request variables and local variables (scope = VARIABLES) act and can be
treated in EXACTLY THE SAME WAY, with the exception that request variables
can go across the <CFMODULE/CUSTOM TAG> boundary, while local variables are
"isolated" to the page and <CFINCLUDE>.
Local variables: die with the page request
Request variables: die with the page request
Local variables:
available in all <CFINCLUDED> code
Request variables:
available throughout the cascading chain of <CFINCLUDE> AND
<CFMODULE> code.
If you know how local variables work, then you know how request variables
work!
STOP THINKING SO HARD!
(but please do yell at Allaire for the lack of documentation that caused
your headache!)

Subject: What are the recognized CF variable scopes?
