  // should remain open for the lifetime of the WebSocket. Data to send over the
  // WebSocket should be written to the producer end of the |send_stream|.
  // |web_socket| will be already connected. There is no need to call Connect()
  // on it. But |client| will still receive a DidConnect() notification.
  //
  // NOTE: WebSocket server support is not fully implemented. For now the
  // following are not supported:
  // - negotiating subprotocol or extension;
  // - fragmented or non-text messages;
  // - failure or close notification;
  // - flow control.
