How to get raw URL from Owin?

Question

How can I get a raw URL from Owin (the URL that was passed to the HTTP request), independently on Owin hosting?

For example, http: // localhost / myapp and http: // localhost / myapp / contains in IOwinRequest.Path /. PathBasealways contains /myapp, but Uri.OriginalStringalways contains http: // localhost / myapp / .

(In ASP.NET, I would say HttpContext.Current.Request.RawUrlthat returns either /myappor /myapp/.)

Reason: Currently, I need to do a server-side redirection to add the final /one if it is missing (regardless of the hosting).

You can get the raw URL in Owin by referring to the HttpListenerContext that was used to receive the request.

    public static string RealUrlFromOwin(HttpRequestMessage request)
    {
        var owincontext = ((OwinContext) request.Properties["MS_OwinContext"]);
        var env = owincontext.Environment;
        var listenerContext = (System.Net.HttpListenerContext) env["System.Net.HttpListenerContext"];
        return listenerContext.Request.RawUrl;
    }

This will not only restore things like trailing / in Url, but also get the Url string before any decoding is applied so that you can distinguish between '!' and% 21, for example.
