title: Why can't I fetch wikipedia pages with LWP::Simple?
body: <p>I'm trying to fetch Wikipedia pages using <a href="http://search.cpan.org/dist/libwww-perl" rel="noreferrer">LWP::Simple</a>, but they're not coming back. This code:</p>
  
  <pre><code>#!/usr/bin/perl
  use strict;
  use LWP::Simple;
  
  print get("http://en.wikipedia.org/wiki/Stack_overflow");
  </code></pre>
  
  <p>doesn't print anything. But if I use some other webpage, say <code><a href="http://www.google.com" rel="noreferrer">http://www.google.com</a></code>, it works fine. </p>
  
  <p>Is there some other name that I should be using to refer to Wikipedia pages? </p>
  
  <p>What could be going on here?</p>
