The problem is that makemap downcases the keys by default so Commonwealth
is commonwealth in the map. Use the -f flag when building the map to
disable this behavior.
Since you're always scanning the db linearly, though, using a DB map
isn't buying you anything. I'd just read the patterns from the text
file directly.

Gratuitous unsolicited style tip #1: Don't put semicolons after a
closing brace except for do and eval blocks, and sub ref constructors.
Gratuitous unsolicited style tip #2: This code would more idiomatically
be
print "$url==>" if $debug;
while (($key, $record) = each %redir_db) {
if ($url =~ s/$key/$record/) {
print $url;
last;
}
}
print "\n";
