Hello everyone, I'm new to perl, just a question for you experts.
I'm trying to automate a procedure that connects to a https login page through a proxy server in my company.
Follow the code I produced:

#!/usr/bin/perl
use strict;
use WWW::Mechanize;
use HTTP::Cookies;
use HTTP::Request;

print "
WWW::Mechanize $WWW::Mechanize::VERSION
LWP $LWP::VERSION
";


my $webpage = '';
my $outfile = "out.htm";

my $url = "https://xxxxx.it";
my $username = "xxxxxx";
my $password = "xxxxxx";
my $mech = WWW::Mechanize->new();

my $cookie_jar = HTTP::Cookies->new( autosave => 1, file => "cookies.t
+xt");

$mech->env_proxy();
$mech->get($url);
$mech->cookie_jar($cookie_jar);
$mech->form_name('Login');
$mech->field(IDToken1 => $username);
$mech->field(IDToken2 => $password);
$mech->click();
#$mech->submit();

my $output_page = $mech->content();
open(OUTFILE, ">$outfile");
print OUTFILE "$output_page";
close(OUTFILE);

print $cookie_jar->as_string, "\n";

without the proxy this seems to be working but if i try using the proxy server it doesn't work giving me back the following exit code:
400 Bad Request
Any ideas ?
Many thanks in advance.
