Easily done with a standard server. Set up a CGI script that's pointed to
by a URL that doesn't indicate it's a CGI. Now, note that many servers let
you add on more path info to a CGI URL and pass it to the CGI script in the
env. For instance, http://www.mydomain/script/111 and
http://www.mydomain/script/112 can activate the same script with a
different argument (which happens to be a number). Set up the CGI so it
reads the rest of the URL after it's own location as a sequence number, and
returns a text/html response that starts with the next number in the
sequence. No human should have patience to get to 100, particularly if the
link is the only thing there.
