Enable HttpResponse.SuppressFormsAuthenticationRedirect

[twsouthwick]

Summary

From the docs:

   /// <summary>
   /// By default, the FormsAuthenticationModule hooks EndRequest and converts HTTP 401 status codes to
   /// HTTP 302, redirecting to the login page. This isn't appropriate for certain classes of errors,
   /// e.g. where authentication succeeded but authorization failed, or where the current request is
   /// an AJAX or web service request. This property provides a way to suppress the redirect behavior
   /// and send the original status code to the client.
   /// </summary>

In scope

• System.Web.HttpResponse.SuppressFormsAuthenticationRedirect
