AS3WebSocket
ActionScript client implementation for the WebSocket Draft RFC6455
...It’s designed to allow Flash/AIR applications to connect via WebSocket (including secure WebSocket: wss://) to servers implementing that standard, to send/receive text and binary data, handle subprotocols, and support fragmentation etc. A test app is included. The testApp directory contains a Flash Builder 4.6 Air Project that uses the AS3WebSocket library and implements two of the test subprotocols from Andy Green's libwebsockets test server, the dumb-increment-protocol, and the lws-mirror-protocol.
