Do a quick comparison between HTML::Mason and Template::Tolkit.
They have many outstanding features, but they are not the same.
My preferences is for Template::Toolkit, but like so many things, I 
think it is very dependant on the job you are doing, and therefore I 
would not push for one over the other unless I knew all the variables 

Good luck.

It isn't as broken as you might think. If you use Digest Auth, there is 
no problem with password security. And most browsers these days support 

I would actually say that most cookie logins are broken as people are 
trying to implement their own authentication. The one thing that Basic 
Auth has wrong is clear text passwords. But that is only because you 
use HTTP. Even the cookie methods require HTTPS, and in HTTPS even the 
Basic Auth passwords are encrypted.

Digest gives you unencrypted HTTP but protected passwords.

You can do single sign on. My Basic Auth module looks at headers first 
and then decides whether to allow through OR send back a 405.

But sign out is a problem. There is an example Apache module (in Perl) 
which does this, but only works on a subset of browsers and relies on 
the browser honouring it. So that may be the show stopper for Basic 
auth for you.

Have fun with your selections :-)
