CGI basics:
1. Write an executable program that produces a "Content-Type:..." header and
two newlines. CHECK
2. Give executable permissions for the webserver (usually wwwrun) to it.
Making it executable to anyone works, too.
3. Place the executable in a place where the web server finds it. If you run
apache, this usually is <SERVER_ROOT>/cgi-bin/
4. Enable CGI extension and the <SERVER_ROOT>/cgi-bin/ path in the webserver
config. You should read the web servers documentation to find out how to do
it.
5. Restart the Webserver/make it reload it's configuration.
6. Type http://<ADDRESS>/cgi-bin/hello_world.pl
BTW: CGI does work with any programming language -- it's named *C*ommon
*G*ateway *I*nterface. If you don't feel comfy with perl, you can choose any
other language you like.
Kind regards
