title: Why urllib.urlopen.read() does not correspond to source code?
body: <p>I'm trying to fetch the following webpage:</p>
  
  <pre><code>import urllib
  urllib.urlopen("http://www.gallimard-jeunesse.fr/searchjeunesse/advanced/(order)/author?catalog[0]=1&amp;SearchAction=1").read()
  </code></pre>
  
  <p>The result does not correspond to what I see when inspecting the source code of the webpage using Google Chrome for example.</p>
  
  <p>Could you tell me why this happens and how I could improve my code to overcome the problem?</p>
  
  <p>Thank you for your help. </p>
