CGI::Application is perfectly cromulent but I think it’s not good advice at this time. It’s a step up from CGI but anyone who was doing best practices with CGI, dispatch tables and request cycle oriented code, was already doing most of what CGI::App does. There are many frameworks now that are superior and easier after the learning curve is done. Including but not limited to Catalyst, Mojolicious, Amon2, and (not my pick but a lot of devs like it) Dancer.

Disclosure, I like cPanel. :P
