in reply to Running a cgi script from index .html
TIMTOWTDI. Do you have SSI available? Enable them for your index.html and use some 'exec cgi' command. Or just make index.html a Perl Program and tell the webserver it is one. Do you have a possibility like mod_rewrite? Just rewrite index.html to whatever script URI you want.
You see, this is more a problem of how to configure your server, not neccesarily a Perl problem. Anyways, I'm sure the Perlmonks can help you if you tell us what webserver you're using.
