Constructor Detail

WebSocket13FrameDecoder

public WebSocket13FrameDecoder(boolean expectMaskedFrames,
                               boolean allowExtensions,
                               int maxFramePayloadLength)

Constructor

Parameters:

expectMaskedFrames - Web socket servers must set this to true processed incoming masked payload. Client implementations must set this to false.

allowExtensions - Flag to allow reserved extension bits to be used or not

maxFramePayloadLength - Maximum length of a frame's payload. Setting this to an appropriate value for you application helps check for denial of services attacks.

WebSocket13FrameDecoder

public WebSocket13FrameDecoder(boolean expectMaskedFrames,
                               boolean allowExtensions,
                               int maxFramePayloadLength,
                               boolean allowMaskMismatch)

Constructor

Parameters:

expectMaskedFrames - Web socket servers must set this to true processed incoming masked payload. Client implementations must set this to false.

allowExtensions - Flag to allow reserved extension bits to be used or not

maxFramePayloadLength - Maximum length of a frame's payload. Setting this to an appropriate value for you application helps check for denial of services attacks.

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