title: Django ALLOWED_HOSTS vs CORS(django-cors-headers)
body: <p>What is the difference between ALLOWED_HOSTS and CORS. If I have defined ALLOWED_HOSTS do I need to define also CORS? I am not using django templates.
  Also do I have the possibility to define those two dynamically?(I think not)<br>
  I am using django as backend, and multiple reactjs frontend apps on different hosts.</p>
