httpwebrequest get url after redirect

السلام عليكم

ازاى اظهر الرابط بعد التحويل؟

مثلا https://goo.gl/b3k9Bn

عند انتهاء تحميل الطلب

سوف يكون الرابط

https://www.instagram.com/accounts/signu...cess_token=...................

ازاى اظهره فى رسالة ؟

عبر الاتصال ب httpwebrequest

جربت

كود :

Dim uurl As String = "https://goo.gl/b3k9Bn"
        Dim request As HttpWebRequest = DirectCast(HttpWebRequest.Create(uurl), HttpWebRequest)
        request.Method = "GET"
        request.KeepAlive = True
        request.CookieContainer = mycontainer2
        request.UserAgent = "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:44.0) Gecko/20100101 Firefox/49.0"
        request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"
        request.ContentType = "application/x-www-form-urlencoded"
        Dim response As HttpWebResponse = Nothing
        response = DirectCast(request.GetResponse(), HttpWebResponse)
        Dim str2 As String = New StreamReader(response.ResponseUri.AbsoluteUri).ReadToEnd

ولكن يظهر خطأ 404 فى هذا السطر

response = DirectCast(request.GetResponse(), HttpWebResponse)

ياترى فى حل؟؟
