Gunicorn - HTTP and HTTPS in the same instance?

[Albert-Jan Roskam]

   I always use NGINX for this. Run Flask/Gunicorn on localhost:5000 and have
   NGINX rewrite https requests to localhost requests. In nginx.conf I
   automatically redirect every http request to https. Static files are
   served by NGINX, not by Gunicorn, which is faster. NGINX also allows you
   to easily set the transfer encoding to gzip
