Ditum Ne Agas:   Do Not Do A Thing Already Done.

What you are describing is “a RESTful application,” and there's no good reason to do that yet again. It's already been done. And, done well. Look at things like Catalyst and other existing Perl frameworks which you might be able to apply to your goals.

Programmers “instinctively” jump to the conclusion that they must write a new application, but let's face it:   ain't too much really new in this world, and there's no point in doing yet-again what has already been done. Just hitch a ride on a passing starship and go.

“I don't want to invent a warp engine! I want to get to Alpha Centauri in time for dinner!”
