  ### <a id='force-https'></a>About FORCE_HTTPS with Reverse Proxies 
  
  If you are using a reverse proxy such as CloudFlare and you have rules to redirect HTTP, do not use FORCE_HTTPS. 
  This is because the reverse proxy is intended to communicate directly with the app through HTTP.
  Forcing the reverse proxy to communicate with the app can cause redirect loops.
  
  The diagram below illustrates a HTTPS redirect loop and direct HTTP communication between a reverse proxy and an app server.
