strange HTTP scan/attack?

[Jim Bacon <jim () TRITECH ORG>]

I am seeing someone repeating hitting a CGI script with a HEAD request and
then submitting a query of the form:

http://blah.blah.blah/cgi-bin/cgiscript/0/0/0/Angola
http://blah.blah.blah/cgi-bin/cgiscript/0/0/0/England
http://blah.blah.blah/cgi-bin/cgiscript/0/0/0/0/Angola
http://blah.blah.blah/cgi-bin/cgiscript/0/0/0/0/England

Where it cycles thru a list of all country names, then starts over with
another 0 in the query string.

This is coming into my server almost as fast as possible, and is somewhat
annoying.

Can anyone offer any clues tp what this is and what I can do about it?  It
appears to be originating from a UUnet dialup in the UK, so any complaints
to a live human are impossible and email complaints just an excercise in my
typing practice.

Thanks!

Jim
