WebSocketServerHandshakerFactory

public WebSocketServerHandshakerFactory(String webSocketURL,
                                        String subprotocols,
                                        boolean allowExtensions)

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. Null if sub protocols not supported.

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

WebSocketServerHandshakerFactory

public WebSocketServerHandshakerFactory(String webSocketURL,
                                        String subprotocols,
                                        boolean allowExtensions,
                                        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. Null if sub protocols not supported.

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.

                                        boolean allowMaskMismatch)

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. Null if sub protocols not supported.

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.

allowMaskMismatch - When set to true, frames which are not masked properly according to the standard will still be accepted.
