title: Pylons, cookies not being destroyed
body: <p>I am trying to remove a cookie called "session" to logout a user.</p>
  
  <pre><code>request.cookies.pop('session', None)
  response.set_cookie('session', '', max_age=-100, domain='.example.org')
  response.set_cookie('session', '', max_age=-100, domain='www.example.org')
  response.delete_cookie('session', '', domain='.example.org')
  response.delete_cookie('session', '', domain='www.example.org')
  </code></pre>
  
  <p>As you can see, I am literally trying everything right now.</p>
  
  <p>Nothing seems to erase the cookie.</p>
  
  <p>Any help is appreciated.  </p>
  
  <p>Thank you!</p>
