Yes. It's just a sub-part of the session hash.

No, that replaces the $Values hashref with an empty one, but doesn't 
remove the values from the main session hashref. Instead, do:

%$Values = ();

That's an empty list, not an empty anonymous hash.

Normally people set values with [update values] after a form post; that 
copies CGI parameters into values space in the session so they're 
available on subsequent pages.
