>                  = post_https(
>                             $server, $port, $script,
>                             make_headers( %header ),
>                             make_form(    %$query ),
>                                          );
>                  my $header_string = '';
>                  for(keys %reply_headers) {
>                          $header_string .= "$_: $reply_headers{$_}\n";
>                  }

Investigate the use_wget option in later Interchanges.
