That looks quite interesting, but unfortunately I'd like to support both Windows and Unix systems.

I'll take a look at luv, thanks. There are a few bindings of libuv around.

I'm working on creationix/luv again thanks to recent interest in the project. Luv itself doesn't do https or tls, but the http parser in luvit is also packaged standalone as creationix/lhttp_parser on github. Tls would be harder, but someone could extract the openssl bindings out from luvit.

Or if you want the controlled route, luvit runs on windows and unix systems and has all that built-in. It's just a little more opinionated and doesn't work out of the box with most existing lua libraries.
