As per discussion in in #8 (primary mode of deployment is with mod_wsgi):

* Comment out the header setting at Django side and also move it from
  settings.py to local_settings.py (because it's now a customizable item).
* Change the header name to ````X-Forwarded-Protocol: https````
* Change the Apache recommendation to use the header name and take it out of
  the mod_uwsgi snippet - and instead add a new section describing
  mod_proxy_http as an option.
