When you configure a cgi script for any server, it may ask you to set variables such as the base, relative, and CGI directory/url settings.

Your home directory on our servers will be /home/USERNAME

Your webpath will be
/home/USERNAME/public_html

which will serve:
http://www.your_domain.com/

So if you need the path to your cgi-bin it would be:
/home/USERNAME/public_html/cgi-bin/

which would serve:
http://www.your_domain.com/cgi-bin/
