Mongrel2 is "Self-Hosting". Zed Shaw’s Mongrel2 is shaping up to be a really interesting project. “A web server simply written in C that loves all languages equally”, the two most interesting new ideas are the ability to handle HTTP, Flash Sockets and WebSockets all on the same port (thanks to an extension to the Mongrel HTTP parser that can identify all three protocols) and the ability to hook Mongrel2 up to the backend servers using either TCP/IP or ZeroMQ. I’m guessing this means Mongrel2 could hold an HTTP request open, fire off some messages and wait for various backends to send messages back to construct the response, making async processing just as easy as a regular blocking request/response cycle.
