[DotNetDevelopment] URL redirect help HttpWebRequest/StreamReader

[netdev1]

How can we extract a final destination url from code using the
httprequest object after a redirect?


sample:

string url = "http://url1.com";;

//url1.com re-directs to url2. How can we get the url for url2 in
code?

WebRequest obj1 = System.Net.HttpWebRequest.Create(url);
            obj = obj1.GetResponse();
            using (StreamReader sr = new StreamReader
(obj.GetResponseStream()))
            {
                r = sr.ReadToEnd();
                sr.Close();
            }

Thank you.
