Well the problem with transparent. Is that you won't by nature usually
get domains that are non-resolvable. The clients browser does all that
before ever sending the request.

Of course you can still get requests where a virus has edited the
clients hosts file, or is sending a request itself directly. Or the
requests where the client can resolve DNS for some weird reason your
proxy can't.

But in general intercepted traffic will all resolve.
