Instead of doing this myself, I would look at one of the asynchronous frameworks, which all can handle that.

See threads, AnyEvent, Mojolicious and IO::Async. There likely are more, but I boldly assume that all of them handle HTTP requests incoming and outgoing.

If you have too much code written for your custom socket to rewrite for another framework, then running the HTTP part in a thread or separate process might be an approach that gives you only complete requests that can be read blocking.
