Long story short

I use https for my project but i see http in self.request.scheme.

In nginx i describe proxy_set_header X-Forwarded-Proto $scheme;

in self.request headers i see 'X-Forwarded-Proto': 'https'

Unfortunately I did not find where the request points X-Forwarded-Proto to like X-Forwarded-For (also did not find it).

I use Ubuntu 16.04 and nginx.
