- SSL Middleware AWS Cloud
- 0 (after 0 ratings)
When using Amazon's ELB with SSL termination, Django needs to know that the requests are secure. You need to use the special indication given on the request (HTTP_X_FORWARDED_PROTO) to determine that. This middleware will do that for you.
The second part is forcing requests to HTTPS in case they are not. This part is not mandatory and could probably be done using configuration rules in your HTTP server. Note that I did it for the specific site, simply to avoid redirecting requests which are not of interest in the first place.
This snippet is based on work done in Django-Heroism.

from django import http class CloudMiddleware(object): def process_request(self, request): if 'HTTP_X_FORWARDED_PROTO' in request.META: if request.META['HTTP_X_FORWARDED_PROTO'] == 'https': request.is_secure = lambda: True return None host = request.get_host() if host.find('example.com') >= 0: new_url = 'https://%s%s' % (host, request.get_full_path()) return http.HttpResponsePermanentRedirect(new_url) return None
