Examples of io.undertow.conduits.PipeliningBufferingStreamSinkConduit

io.undertow.conduits.PipeliningBufferingStreamSinkConduit
A buffer that is used when processing pipelined requests, that allows the server to buffer multiple responses into a single write() call.
This can improve performance when pipelining requests. @author Stuart Douglas
