What interfaces you mean? TCPConnector... Well, the conenct method is
not blocking, I have to use a callback and I have to remember the whole
time to byteBuffer I want to write and must care if in the meanwhile new
read request are coming in and keep the correct order. This sounds
painful. I have tried your tunnel implementation but it lasts more or
the same time than mine.

No, the map contains the SocketConnections from the client to the proxy
as key and proxy to server as value and also the other direction.

The largest one, everything which is non blocking. non blocking large
file and non blocking small page.
