Whoops, perlmonk.org is currently down, so until http://jdporter.perlmonk.org/cgi_course/ comes back online

And until http://web.archive.org/web/20100825091937/http://jdporter.perlmonk.org/cgi_course/ comes back online

Try http://web.archive.org/web/20070709150107/http://users.easystreet.com/ovid/cgi_course/

In any case, the -nosticky and url_param portions of the CGI docs is what you want
