body: <p>Under Python 3.1, when trying to run this code: </p>
  
  <pre><code>from urllib import request
  
  def test():
      request.urlopen("http://www.google.com")
  
  test()
  </code></pre>
  
  <p>I get an HTTP 409 error. The stack trace is:</p>

  </code></pre>
  
  <p>And the actual error, as printed, is:</p>
  
  <pre><code>urllib.error.HTTPError: HTTP Error 409: Conflict
  </code></pre>
  
  <p>I'm behind a proxy set via a configuration script; I've had no issues regarding internet connection.</p>
  
  <p>Why on earth am I getting an HTTP 409 error?</p>
