in reply to How to make relative URL if "cgi-bin" is above the web root?

Without commenting on the rest, I just noticed this:
$docfile = "../../htdocs/cowboys/$FORM{'3'}";
That's an attack vector accident just waiting to happen.

If you're creating this code, you need to read up on web security. A lot.

If you're just configuring it, please pass my concern along to the author.
