How to get 302 redirected url from an existing url in asp.net c#

thanks for the comment kaufmed.

I have slightly altered the code. response.StatusCode is always 'OK' even when there is a redirect. I m comparing the response.ResponseUri with the original URL and its seems to be working though for only initial two requests but starts timing out then. I have a list of 13000 urls to test in a loop and wondering if that is possible. My code as below

 class Program
    {
        static void Main(string[] args)
        {
             string line;
            // Read the file and display it line by line.
            System.IO.StreamReader file =   new System.IO.StreamReader(@"C:\Users\MehtabM\Documents\URIFiles\ScotGov1.txt");

            List<string> href = new List<string>();

            while ((line = file.ReadLine()) != null)
            {
              href.Add(line);
            }

            file.Close();

            HttpWebRequest request; 
            HttpWebResponse response;
            

            foreach(string item in href)
            {
                request=HttpWebRequest.Create(item) as HttpWebRequest;
                request.Method = "GET";
                request.ContentType = "text/xml";
                response = request.GetResponse() as HttpWebResponse;


                if (response.ResponseUri.ToString() != item)
                {
                    item.Replace(item, response.ResponseUri.ToString());
                }
                response = null;

            }

           


        }
    }

thanks again kaufmed for the help.

If I change the  request.Method = "HEAD" This way we will not load whole page. Server only returns the headers and does not block subsequent requests.
