Ok - but where is the response supposed to go?

Remember that HTTP is about a client sending a *request* and the server
returning a *response*. The whole idea implies a one-to-one mapping
between client and server. If you somehow clone a request and fan it out
to another server, you create two responses to the same request. How is
the client supposed to handle this? If you're talking about a purely
research environment, you could invent a client that handles two
responses, but no real-world browser can handle this.

Maybe you plan to trap the response from the test server and short it to
ground? Then you'd need to configure the test server (at the TCP/IP
level - not HTTP) to route all outgoing traffic to a machine that
terminated the TCP/IP traffic (ie, acknowledged it) but didn't deliver
it further. That would be a router, I guess... by now you're into
network-layer programming and have left HTTP behind.
