You almost had it! First, you'll probably want to tweak the HREF link just a bit:
http://www.domain.com/cgi-bin/pgbuilder.pl?dir=archimage
Then, the Perl code:
use strict;
use CGI qw/ :standard /;
my $dir = param( 'dir' );
However, this could be a problem. What, exactly, is 'dir' supposed to contain and how
do you want
to open that directory? If you are opening directories and serving content directly
from them,
you could have some serious security issues. Unfortunately, security is very
difficult to get
right. One example of how this can go horribly wrong is at
http://www.perlmonks.org/index.pl?node_id=36121
If you can post some more of your code (particularly what you're doing with $dir), we
can go over
it and let you know if there are any issues that you may want to address.
