title: Why can't Django find my admin media files once I leave the built-in runserver?
body: <p>When I was using the built-in simple server, everything is OK, the admin interface is beautiful:</p>
  
  <p><code>python manage.py runserver</code></p>
  
  <p>However, when I try to serve my application using a wsgi server with <code>django.core.handlers.wsgi.WSGIHandler</code>, Django seems to forget where the admin media files is, and the admin page is not styled at all:</p>
  
  <p><code>gunicorn_django</code></p>
  
  <p>How did this happen?</p>
