Question

I have the following code:

public static string FormatHostAndUrl(this HttpSessionStateBase session)
    {
        var a = session["CurrentHost"];
        var b = session["CurrentUrl"];
        var c = string.Format("http://{0}{1}", session["CurrentHost"], new Uri((string)session["currentUrl"]).PathAndQuery);
        return string.Format("http://{0}{1}", session["CurrentHost"], new Uri((string)session["currentUrl"]).PathAndQuery);
    }

I use this to get the exact URL including Port. With the azure system I am using this seems to be the only combination of code that gives the correct URL.

I get the session variables

Session["CurrentUrl"] = Request.Url.ToString();
Session["CurrentHost"] = Request.Headers["Host"];

What I would like to do is to extend the Request object so I can do something like this:

Session["TheRealURLI Need"] = Request.RealURL();

Is it possible to do this with an extension method? Some method that does the functionality of the FormatHostAndUrl method?

Answer 1

public static class Extensions
{
    public static string GetRealUrl(this HttpRequest request)
    {
        return "will the real url please stand up?";
    }
}

Edit: The point here is you extend classes, even sealed ones. How you get the HttpRequest object is irrelevant, whether it’s via a Request property or by any other means. You extend the type. The property will follow suit.
