@cusspvz can you please review this PR?

I think there are too many changes for PR, I'll do a fork

Hey @gugu,

first of all, thank you so much for contributing to this project. Right now I've still a lot of stuff on my plate, so I have this PR open on my computer for a while. I'm really interested in merging your contribution but I have to review and test it. I'm going to reopen this, but in case you need this upfront, I'd advise you to create your own fork and use it directly until we get this merged.

Thank you, looking forward to merging this and sorry for letting you in the dark!

Let's keep this in draft state (now it has a major rewrite to support http2 and bugfix when socket.setTimeout() did not work on proxied server)

When you review this PR, I'll remove @short.io attribution from README and package.json so it would be possible to merge it
