How can you tell if a request came in via HTTP vs. HTTPS? in Visual Studio

Question

Using Visual Studio 2017, I'm building an ASP.NET Core site.

How can you tell, in the controller, if a web request came in via HTTP vs. HTTPS?

Answer 1

Use Request.IsHttps

public IActionResult Index()
{
    var isSecure = Request.IsHttps;

    // Do Something

    return View();
}
