     int maxFramePayloadLength)

    Constructor specifying the destination web socket location

    Parameters:

    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 protocols

    maxFramePayloadLength - Maximum allowable frame payload length. Setting this value to your application's requirement may reduce denial of service attacks using long data frames.
