title: Django: Dynamically set SITE_ID in settings.py based on URL?
body: <p>What is a good way to dynamically set SITE_ID in settings.py based on domain name in URL?</p>
  <p>I have an app that will be running with too many domain names (city based) that a custom settings.py file for each domain is just not doable.</p>
  <p>Is there a way to set it dynamically?</p>
