Venerable monks, if I use the following code to retrieve HTML from the following addresses (my browser displays them without a problem):

#! /usr/bin/perl
use strict;
use warnings;

use LWP::UserAgent;

my $url_1 = 'http://www.springerlink.com/content/w63801m75p4hr012/';
my $url_2 = 'http://www.sciencedirect.com/science/article/pii/S1439179
+111001204';

my $browser = LWP::UserAgent->new;

for my $url ( $url_1, $url_2 )
{
    my $response = $browser->get( $url );   

    my $html = $response->is_success
        ? $response->content
        : warn $response->status_line;
}

I get: 

403 Forbidden at monks_sample.pl line 15.
400 Bad Request at monks_sample.pl line 15.

Any ideas? Thanx!
