Get a collection of redirected URLs from HttpWebResponse

Question

I\'m trying to retrieve a list of urls that represent the path taken from URL X to URL Y where X may be redirected several times.

Answer 1

There is a way:

public static string RedirectPath(string url)
{
    StringBuilder sb = new StringBuilder();
    string location = string.Copy(url);
    while (!string.IsNullOrWhiteSpace(location))
    {
        sb.AppendLine(location); // you can also use 'Append'
        HttpWebRequest request = HttpWebRequest.CreateHttp(location);
        request.AllowAutoRedirect = false;
        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
        {
            location = response.GetResponseHeader("Location");
        }
    }
    return sb.ToString();
}

I tested it with this TinyURL: http://tinyurl.com/google
Output:

http://tinyurl.com/google
http://www.google.com/
http://www.google.be/?gws_rd=cr

This is correct, because my TinyURL redirects you to google.com (check it here: http://preview.tinyurl.com/google), and google.com redirects me to google.be, because I'm in Belgium.
