The extension is disabled by default on the server and enabled by default on the client. Use the wss:// protocol (WebSockets over TLS). Hard code the URL of the WebSockets endpoint, and certainly don't incorporate user-controllable data into this URL. Protect the WebSocket handshake message against CSRF, to avoid cross-site WebSockets hijacking vulnerabilities. Treat data received via the WebSocket as untrusted in both directions. The WebSocket protocol specification defines ws (WebSocket) and wss (WebSocket Secure) as two new uniform resource identifier (URI) schemes that are used for unencrypted and encrypted connections, respectively.
