NEED HELP with CGI (Back Links)

["scorpiusb2000" <scorpiusb2000@yahoo.com>]

I'm trying to set up a CGI script for Back Links that I got from 
WAXY.ORG.  The instructions are set up for UNIX.  My problem is, I 
have Windows.  The instructions state:

# The directory where you want to store the backlink files.
# Note: must be writable by your web server
my $backlinkdir = '/usr/local/apache/htdocs/backlink_cache';

Can I chnage: 
($backlinkdir = '/usr/local/apache/htdocs/backlink_cache';)

to 

$backlinkdir = 'http://www.story.com/backlink';

I just need to know if this is right, and will it work?
