I asked a similar question on HTTPwg a while back, and got a few interesting
responses. Check the mailing list.

Probably the best is from Jim Gettys:

Digest auth definately has this capability, and is (more) secure.
Unfortunately, there still aren't many browsers who support Digest (haven't
checked with the latest, but if any of your users use even moderately old
ones, you're out of luck).

Hope this helps,
