title: OWIN in ASP.NET - Force HTTPS redirection in website
body: <p>I wonder if it's suitable to force HTTPS redirection for an whole website in a OWIN module? How can this be implemented?</p>
  
  <p>Currently I'm using the globally registered filter named "RequireSSLAttribute" which is built-in in the ASP.NET MVC framework.</p>
  
  <p>I'm not happy with this standard functionality since it's only able to do temporary redirections and not permanent redirections which is better from an SEO perspective. I have found information that permanent redirections is included in MVC6.</p>
  
  <p>Are there any pros/cons with implementing HTTPS redirection in a OWIN module instead of using the "RequireSSLAttribute" filter in ASP.NET MVC?</p>
