org.apache.synapse.transport.nhttp.util.PipeImpl
Create a Pipe suitable for the runtime platform. The java.nio.channels.Pipe implementation on Windows uses TCP ports bound to the loopback interface to implement a Pipe. In Linux and Solaris this is passed to a native method.

            HttpResponse response = responseFactory.newHttpResponse(
                httpVersion, HttpStatus.SC_OK, context);
