...Alongside, if --threadless is enabled, ThreadlessPool is setup which starts Threadless processes (--num-workers) to handle the incoming client connections.

HttpProtocolHandler simply assumes that incoming clients will follow HTTP specification. Specific HTTP proxy and HTTP server implementations are written as plugins of HttpProtocolHandler.
