I don't do POSTing like that. Here is how I do it:

-- snip --

sub connect_via_dispatch {

   my $curl = Curl::easy::init();

   if(!$curl) {
      die "curl init failed!\n";
   }

   my $url = "https://www.url.cc/cgi-bin/script.cgi";
   my $rawHTML = ""; # Stores the HTML returned from curl
   $::errbuf = "";
   Curl::easy::setopt($curl, CURLOPT_ERRORBUFFER, "::errbuf");

   Curl::easy::setopt($curl, CURLOPT_URL, $url);
   Curl::easy::setopt($curl, CURLOPT_NOPROGRESS, 1);
   Curl::easy::setopt($curl, CURLOPT_TIMEOUT, 30);
   Curl::easy::setopt($curl, CURLOPT_HEADERFUNCTION, \&header_callb);
   Curl::easy::setopt($curl, CURLOPT_WRITEFUNCTION, \&body_callb);
   Curl::easy::setopt($curl, CURLOPT_POST, 1);
   Curl::easy::setopt($curl,
CURLOPT_POSTFIELDS,"Service=CDR&PIN=$DC&StartDate=$prev_m-$prev_d-$prev_y&EndDate=$endmonth-$endday-$endyear&PageItems=99999999&Offset=-6");
   Curl::easy::setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
   Curl::easy::setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
   Curl::easy::setopt($curl, CURLOPT_SSL_VERIFYHOST, 1);
   Curl::easy::setopt($curl, CURLOPT_USERAGENT, "Mozilla/4.0");
   Curl::easy::perform($curl);
   Curl::easy::cleanup($curl);
}

sub body_callb {
   my($chunk,$handle)=@_;
   ${handle} .= $chunk;
   $rawHTML .= $chunk;
# print $rawHTML;
   return length($chunk);
}

sub header_callb {
   return length($_[0]);
}
