Redirect without rewriting host portion of URL

If you want to hide the change in hostname from the client you would want to rewrite the Host header value and potentially select a different pool to send the requests to. You wouldn't want to send a redirect back to the client as this will update the address bar and the client will see the change. Is there a separate pool that serves content for mydomain2.com? Or is it the same as mydomain1.com?
