[prog] session management with Perl CGI scripts

[Dan Richter]

Does anyone know of a simple program that demonstrates session management 
(over the web) in Perl? For example, a CGI program where you have to login?

What I'm particularly interested in is how automated the system is. I think 
I noticed somewhere a module that makes it easy to maintain data associated 
with a session. Does anyone know what this module might be?

   on humans, but not to test absorption of an oral pill. Because a
   pill was much more practical than injections, the scientists bent
   the rules and performed absorption tests -- on themselves.
