Your post isn't very clear on what you are trying to accomplish. As you said, the code you posted will populate the template with the last .*map.* line. Although, you should probably add $vars{'d'} = $1; to fill out your template.

If you just want to spit the file out again, then you can try something like this in your loop:

  $vars{'lines'} = [];
  push @{ $vars{'lines'} }, {'proto' => $4,
                             'uri1'  => $5,
                             'uri2'  => $7,
                             'd'     => $1};

Then you iterate in your template like so:

{ foreach $line (@lines)
  {
    $OUT .= "$line->{'d'} map $line->{'proto'}://$line->{'uri1'} $line
+->{'proto'}://$line->{'uri2'}\n";
  }
}
