Granted this is a server-based session-management solution and requires the installation of Apache webserver and mod_perl (optionally MySQL or PostgreSQL), so YMMV.
Just throw in a Web application development framework like HTML::Mason or Text::Template and you too could be the next amazon.com!!!! :) see princepawn's node for some framework starting points...
<tip>When using server-based session management, instead of storing lots of user data in the session consider storing only the row id from the user's login profile in the session. That way with one quick query to the database on a page reload you have all the user profile information. There are of course pros and cons to this, but for some applications such a technique would be desirable. </tip>
