WebSocketServerHandshaker08

public WebSocketServerHandshaker08(java.lang.String webSocketURL,
                           java.lang.String subprotocols,
                           boolean allowExtensions,
                           int maxFramePayloadLength)

Constructor specifying the destination web socket location

参数:

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

allowExtensions - Allow extensions to be used in the reserved bits of the web socket frame

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