JJUG Cross Community Conference 2014 Fall Proxy WebSocketCONNECT TLS / SSLOK Ajax / Comet 24 _Proxy Usage_: If the client is configured to use a proxy when using the WebSocket Protocol to connect to host /host/ and port /port/, then the client SHOULD connect to that proxy and ask it to open a TCP connection to the host given by /host/ and the port given by /port/. EXAMPLE: For example, if the client uses an HTTP proxy for all traffic, then if it was to try to connect to port 80 on server example.com, it might send the following lines to the proxy server: CONNECT example.com:80 HTTP/1.1 Host: example.com RFC 6455 25.
