Asio + http-parser from Joyent = fun.
You can create your own high performance HTTP based services in seconds. This library uses http-parser library from Joyent which is based on the nginx http parser and powers nodejs.
Uses stand-alone ASIO library and C++11 without the requirement of boost like the original implementation.
