Yes, an ISP I talked to pointed out that most of this activity is
driven by worms. My first attempt at dealing with this problem was to
respond with a redirect to www.yahoo.com after a 10-second delay, but
this actually seemed to stimulate some of the "scanning" computers to
try more often. Maybe not responding at all will cause them to go away.

After a couple of days of operation, quite a few bad requests have
been rejected, and normal operations have not been affected, so I
guess it works. I will go ahead and post it.

Thanks for the comments.
