The secondary server sends the response to the client directly.

Tux accepts the initial port 80 request, and makes a decision. If it
decides to let the secondary server handle the request, it picks up the
file descriptor which describes the network connection to the client and
hands it off to the secondary server. The server sends the response to
the client IP:port info in that file descriptor.
