If the redirect code is in the page itself, you could always find it and parse it by downloading the page with WebClient. Otherwise, you could do a cheap job and make an invisible webbrowser, navigate and get the url from it. Just set the visible property to false.

You can use a web request to check for redirection headers. This works for things like Tiny URL, but not JavaScript redirection.

Public Function GetRedirectionUrl(ByVal Url As String) As String
    Dim Request = TryCast(Net.WebRequest.Create(Url), Net.HttpWebRequest)
    If Request Is Nothing Then Return Nothing
    Request.AllowAutoRedirect = False
    Return Request.GetResponse.Headers("Location")
End Function

Thanks swan and flaming idiots

I didnt really wanna use the invisible web browser, it seemed tacky and unreliable.

But that GetRedirectionUrl function works like a charm, ur a genius
