Get a collection of redirected URLs from HttpWebResponse

c#, httpwebresponse, redirect, url

Solution

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

Press any key to continue . . .

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.

Problem

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. For example: http://www.example.com/foo That will redirect to: http://www.example.com/bar Which then redirects to: http://www.example.com/foobar Is there a way of get this redirect pathway from the response object as a string: `http://www.example.com/foo > http://www.example.com/bar > http://www.example.com/foobar` I'm able to get at the final URL via `ResponseUri` e.g. ``` public static string GetRedirectPath(string url) { StringBuilder sb = new StringBuilder(); HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); using (var response = (HttpWebResponse)request.GetResponse()) { sb.Append(response.ResponseUri); } return sb.ToString(); } ``` But this obviously skips the URL in between. There doesn't seem be an easy way (or way at all?) to get the full pathway?
