[VB.NET] Httpwebrequest "Location" in Response herausfinden?

Ich habe hier folgenden Code aus Livehttpheaders:

Code:
HTTP/1.1 302 FOUND
Content-Language: de
Content-Type: text/html; charset=utf-8
Date: Tue, 23 Apr 2013 14:54:47 GMT
Location: http://statigr.am?code=c19309934fg45e178d0f8581ec5a9318
Server: nginx
Set-Cookie: csrftoken=MEINTOKEN; expires=Tue, 22-Apr-2014 14:54:47 GMT; Max-Age=31449600; Path=/
Set-Cookie: ccode=DE; Path=/
Vary: Cookie, Accept-Language
Content-Length: 0
Connection: keep-alive
Doch wie komme ich jzt in der Response auf die Location?

Code:
Location: http://statigr.am?code=c19309934fg45e178d0f8581ec5a9318
Würde mich über schnelle Hilfe freuen :-)

MfG, maxasoft

Wenn ich mir das dann in ner Msgbox auswerfen lasse, bleibt diese leer.

Code:

Code:
response = CType(request.GetResponse(), HttpWebResponse)
            Dim url As String = response.Headers("Location")
            MsgBox(url)

Ich habs mal so probiert:

Code:
Dim str as string = Response.Headers(0)
Ich hab mir mal die Werte 0-9 ausspucken lassen, allerdings kommt nirgends ne URL und ab 5 oder 6 kommt nur noch das Datum + Uhrzeit

Kenn mich mit Requests nicht so aus & finde nichts was mit Weiterleitung zu tun haben könnte ://

Die übergebe ich mit:

Code:
Dim Request2 As HttpWebRequest = CType(HttpWebRequest.Create(tokenURL), HttpWebRequest)
        'Proxy
        'Request.Proxy = New WebProxy("159.255.166.29:8080")

        Request2.Method = "POST"
        Request2.ContentType = "application/x-www-form-urlencoded"
        Request2.Referer = tokenURL
        Request2.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"
        Request2.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:20.0) Gecko/20100101 Firefox/20.0"

        Request2.CookieContainer = cookieCon
        Dim Post As String = "csrfmiddlewaretoken=" & token & "&username=" & TextBox1.Text & "&password=" & TextBox2.Text
        Dim byteArray() As Byte = Encoding.UTF8.GetBytes(Post)
        Request2.ContentLength = byteArray.Length
        Dim DataStream As Stream = Request2.GetRequestStream()
        DataStream.Write(byteArray, 0, byteArray.Length)
        DataStream.Close()

        Dim Response2 As HttpWebResponse = Request2.GetResponse()
        DataStream = Response2.GetResponseStream()
        Dim reader As New StreamReader(DataStream)
        Dim ServerResponse As String = reader.ReadToEnd()
        reader.Close()
        DataStream.Close()
        Response2.Close()

        RichTextBox1.Text = ServerResponse
Wenn ich allerdings den Quelltext anzeigen lasse, ist das fast der selbe wie vor der Request, also der von der Instagram-Login-Form. ^^

Wenn ich bei einer der Requests AllowAutoRedirect = False verwende, wird aber gar kein Quelltext angezeigt.

Und wenn ich bei der Request oben im 1. Post AllowAutoRedirect = False verwende, bekomm ich unter Location nicht den Statigr.am Link, sondern den Link, an die ich das token & die Logindaten gesendet habe. Der ganze Code für die Request vom 1. Post:

Code:
request = CType(HttpWebRequest.Create("https://instagram.com/oauth/authorize?client_id=" & id & "&redirect_uri=http%3A%2F%2Fstatigr.am&response_type=code&scope=likes+comments+relationships"), HttpWebRequest)
            request.CookieContainer = cookieCon
            request.AllowAutoRedirect = False

            response = CType(request.GetResponse(), HttpWebResponse)
            Dim url As String = response.Headers("Location")
            MsgBox(url)
            Dim sr As New StreamReader(response.GetResponseStream())
            Dim quelltext As String = sr.ReadToEnd
            If quelltext = RichTextBox1.Text Then
                MsgBox("same")
            Else
                MsgBox("other")
                RichTextBox1.Text = quelltext
            End If

        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
