I need some help, am using twilio gather. and am getting the response to my webhook file

but am trying to store the data which twilio sent to my webhook file or url. but its not working

#!/usr/bin/perl

use strict;
use warnings;
use CGI;
use CGI::Cookie;
my $CGI = CGI->new();
my $cont = $CGI->param("Digits");

if ($cont) {

my $Rspn = CGI::Cookie->new(-name  =>  'Response',
                          -value   =>  "$cont",
                          -expires =>  '+50m');
print "Set-Cookie: $Rspn\n";

print "Content-type: text/html\n\n";   # I added this because i want t
+o see the reponse in browser to myself and twilio call log board

print "We have got input: $cont";
}

And this shows that twilio reads our webhook file and is able to post the request successful

What i need is that. when twilio sends request to ur webhook file or url. it should be accepted and store anything that twilio sent to us. via Digits Parameter and store it to cookies
