title: CloudFlare SSL compatibility with ASP.NET MVC RequireHttps
body: <p>I am hosting an ASP.NET MVC 4 site on AppHarbor (which uses Amazon EC2), and I'm using CloudFlare for Flexible SSL.  I'm having a problem with redirect loops (310) when trying to use RequireHttps.  The problem is that, like EC2, CloudFlare terminates the SSL before forwarding the request onto the server.  However, whereas Amazon sets the X-Forwarded-Proto header so that you can handle the request with a custom filter, CloudFlare does not appear to.  Or if they do, I don't know how they are doing it, since I can't intercept traffic at that level.  I've tried the solutions for Amazon EC2, but they don't seem to help with CloudFlare.</p>
  
  <p>Has anyone experienced this issue, or know enough about CloudFlare to help?</p>
