Hmmm. Good point. First cut implementation is probably to offer to tunnel
Accept-* headers (but not by default to avoid 406). Next step would be to
add popups for Accept-Language and Accept-Encoding (allowing you to select
just one of each if you want to check what the server returns).

I don't really see any good way to deal with the other problem you describe
above though. So if anyone has any suggestions I'd be very happy to hear
them!

Thanks. Fixed in CVS.
