I need to access internet page via proxy.
I need to used NTLM or Digest Auth Scheme

The code i get on googling doesn't work.

Below code is going with any Auth Header.
Please help me to get webpage via NTLM proxy auth.

GET (URL address blocked: See forum rules) HTTP/1.1
TE: deflate,gzip;q=0.3
Keep-Alive: 300
Connection: Keep-Alive, TE
Host: google.com
User-Agent: libwww-perl/6.02

my $ua = new LWP::UserAgent(keep_alive => 1);
$ua->proxy('http', $PROXY);
$ua->credentials('proxy', '', 'username','passwd');

my $req = GET  $url;
print "--Peforming request now...---------\n";

my $res = $ua->request($req);
if ($res->is_success) {
    print $res->content;
} else {
    print "Error: " . $res->status_line . "\n";
    print $res->headers()->as_string(), "\n";
