it is possible.
But then you will have to configure the sorryserver as a redirect.
The reason is the CSS must see both side of the traffic.
So if you send it to a remote location, you may not see the response from the server [unless you do client nat].
If you use a redirect, you just tell the client browser to go to the remote location and you don't care anymore to see the server response.
