namespace Infrastructure
{
    /// <summary>
    /// MVC attribute that redirects non HTTPS requests to a HTTPS URI.
    /// </summary>
    public class RedirectToHTTPSAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            HttpRequestBase req = filterContext.HttpContext.Request;
            HttpResponseBase res = filterContext.HttpContext.Response;

            //Check if require is HTTPS
            if (!req.IsSecureConnection)
            {
                var builder = new UriBuilder(req.Url)
                {
                    Scheme = Uri.UriSchemeHttps,
                    Port = 443
                };
                res.Redirect(builder.Uri.ToString());
            }
            base.OnActionExecuting(filterContext);
        }
    }
