The why question is simple...
The link should point to $pod_fullpath./cgi-bin/feedback.cgi
in the demo: http://www.grohol.com/cgi-bin/pod2.c...n/feedback.cgi

But it points to $pod_fullpath.$pod_urlpath.$pod_progname./cgi-bin/feedback.cgi?where=search
in the demo: http://www.grohol.com/cgi-bin/pod2.c...i?where=search

Maybe I will make a fix if someone else doesn't...
