You want to have cookie-based authentication tokens?  No problemo!  The 
PerlAccessHandler gives you this opportunity.  You've got the request 
(and any cookies associated with it), and if you find them acceptable 
you can accept the request.  If they're not, generate a redirect to the 
login page, and you're done.  Obviously you always want to allow people 
to hit the login page.

Even better, this is an example in the mod_perl book, and the sample 
chapter is freely available on-line.  Cruise on over to:


It uses Apache::TicketAccess as the AccessHandler to do the hard work, 
but you can alter this to taste if you like.

The lovely thing about this is that because it hooks in at the Access 
stage, you can still use any technology you like for generating content.
