I'd suggest looking to your web application framework for this

I use Catalyst. To achieve user login with expiring sessions, you need
three plugins: Authentication, Authentication::Store::DBIx::Class and
Session. It is fairly easy to configure everything. This takes care of
everything, including authenticating credentials against a database,
maintaining the session cookie and server side state data. The basics
are spelled out in the Catalyst manual:


There are similar plugins for the other popular web app frameworks.
