Hi Monks,
I encountered a LWP::UserAgent problem in Windows, the perl is running version 5.14.2. Running the following code on Ubuntu 12.04 and ReadHat machine both have no problem. Running it on Win7, 64bit encountering issues. Could you please shed some light here.
Appreciate! 

#!/usr/bin/perl

use warnings;
use strict;
use LWP::UserAgent;

$ENV{HTTPS_DEBUG} = 1;

my @requestHeaders = (
  'Content-type' => 'text/json',
  'username' => 'xxx',
  'password' => 'yyy'
);

my $url = "https://ipaddr:443/dir/dir";
my $ua = LWP::UserAgent->new;
$ua->default_header('Accept-Encoding' => scalar HTTP::Message::decodab
+le());
$ua->add_handler("request_send",  sub { shift->dump; return });
$ua->add_handler("response_done", sub { shift->dump; return });
my $response = $ua->get($url, @requestHeaders);
die "Error $url\n".$response->status_line."\n" unless $response->is_su
+ccess;
print "Success ".$response->content_type. " document!\n";
