If you're tunneling SSH through HTTP, shouldn't it actually be "Any protocol of top of web"?

Also interesting choice to use C++. I don't see the headers for Civet or Mongoose, or even libcurl in the Makefile. Is it your own HTTP implementation on both sides?

It doesn't really need to support the full HTTP spec given that both the client and server are under its control... Any subset will do; all you really need to do is respond with a 200 header.
