HTTP Request Headers in VB.NET

I am attempting to integrate Google Shard contacts with an ASP.NET application. I have successfully implemented the first part of their procedure which is to authenticate the application with the Google account using the code below:

---------------------------------------------------

<script runat="server">

Dim t As String

Sub Page_Load(Sender As Object, E As EventArgs)

      t = Request.QueryString("token")
      
      Dim googleRequest = HttpWebRequest.Create("https://www.google.com/accounts/AuthSubSessionToken")
      googleRequest.Method = "GET"
      googleRequest.Headers.Set("Authorization", "AuthSub token=""" & t & """")
      Dim googleResponse = googleRequest.GetResponse()
      
      outputLabel.Text = googleResponse.toString()
      
End Sub

</script>

---------------------------------------------------

The problem I now have is accessing the content of the "googleRequest.GetResponse()" method.

Please note that I am not necessarily looking for a "Google-specific" answer here (but please feel free to give one) but really an explanation of how to extract the data returned inside the "GetResponse()" method of the HttpWebRequest.

NB: I know it's hard but please do not come back with comments like, "you need to do it in jsp or c# etc!" I am looking for a vb.net solution please.
