So that it is possible to run Web Sockets over port 80 (or 443) and have the HTTP server defer to a Web Socket server on a URL-by-URL basis. Basically the protocol is intentionally HTTP-like to make it possible to use it in environments that are currently expecting HTTP, without in fact requiring people implement HTTP if they don't actually need it. > And also, why not require an empty reason phrase (which would get rid of > having plain text messages in English hardwired into the protocol)? Given that the handshake blob is basically opaque, what's wrong with having hardwired? The previous version had the handshake be just "Hello" "Welcome", which is just as hardwired to English. -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
