title: Where do I set my site url in django settings?
body: <p>Ok I think I must be missing something. In <code>settings.py</code> I don't see the setting for absolute url for the site. I see there is <code>MEDIA_URL</code>.</p>
  
  <p><code>django-registration</code> references <code>{{ site }}</code> which is defaulting to <code>example.com</code> but I'm not seeing that in any settings.</p>
  
  <p>If I want the <code>dev.mysite.com</code> and <code>mysite.com</code> to work independently, what do I need to put in <code>settings.py</code>?</p>
