Why doesn't LWP get html file?

$html has nothing from the following code. Could someone help me?
Thanks.

use LWP;
use URI;
$Browser = LWP::UserAgent->new || die "$!";

my $Surfurl = 'http://us.randstad.com/webapp/internet/servlet/
BranchView?b=702';
my @ns_headers = (
'User-Agent' => 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;
rv:1.8.1.11) Gecko/20071127',
'Accept' => 'image/gif, image/x-xbitmap, image/jpeg, image/pjpeg,
image/png, */*',
'Accept-Charset' => 'iso-8859-1,*,utf-8',
'Accept-Language' => 'en-US',
);

my $response = $Browser->get( $Surfurl, @ns_headers );
die "Can't get $url -- ", $response->status_line unless $response-
is_success;
die "Hey, I was expecting HTML, not ", $response->content_type unless
$response->content_type eq 'text/html';

my $html = $response->decoded_content;

print $html;
print "program finished";
