Django: Forbidden (CSRF cookie not set.)
<p>I am having a problem with "CSRF cookie not set". All I need is that the external billing platform send the update to the django server. Locally it works with Postman but in the demo server its not working...</p>

<h1>Code</h1>

<pre><code># views.py
from django.views.decorators.csrf import csrf_exempt
from django.http import JsonResponse

@csrf_exempt
def postback(request):
    print(request.POST)
    return JsonResponse({'ok': 'hoooh!'})

# urls.py
from django.conf.urls import url
from billing import views

urlpatterns = [
   url(r'^postback/$', views.postback),
]
</code></pre>

<h1>Error</h1>

<pre><code>Forbidden (CSRF cookie not set.): /billing/postback/
[21/Jul/2016 10:49:21] "POST /billing/postback/ HTTP/1.1" 403 2682
</code></pre>

<h1>Result of the postback to the requestb server</h1>
