webSocketURL
- URL for web socket communications. e.g "ws://myhost.com/mypath". Subsequent web
socket frames will be sent to this URL.subprotocols
- CSV of supported protocolsallowExtensions
- Allow extensions to be used in the reserved bits of the web socket framemaxFramePayloadLength
- Maximum allowable frame payload length. Setting this value to your application's
requirement may reduce denial of service attacks using long data frames.protected FullHttpResponse newHandshakeResponse(FullHttpRequest req, HttpHeaders headers)
Handle the web socket handshake for the web socket specification HyBi versions 13-17. Versions 13-17 share the same wire protocol.
