  ' Referer property is set to http://www.microsoft.com
  myHttpWebRequest.Referer = "http://www.microsoft.com"
  ' The response object of 'HttpWebRequest' is assigned to a 'HttpWebResponse' variable.
  Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
  ' Displaying the contents of the page to the console
  Dim streamResponse As Stream = myHttpWebResponse.GetResponseStream()
  Dim streamRead As New StreamReader(streamResponse)
  Dim readBuffer(256) As [Char]
  Dim count As Integer = streamRead.Read(readBuffer, 0, 256)
  Console.WriteLine(ControlChars.Cr + "The contents of HTML page are.......")
  While count > 0
      Dim outputData As New [String](readBuffer, 0, count)
      Console.Write(outputData)
      count = streamRead.Read(readBuffer, 0, 256)
  End While
  Console.WriteLine(ControlChars.Cr + "HTTP Request  Headers :" + ControlChars.Cr + ControlChars.Cr + "{0}", myHttpWebRequest.Headers)
  Console.WriteLine(ControlChars.Cr + "HTTP Response Headers :" + ControlChars.Cr + ControlChars.Cr + "{0}", myHttpWebResponse.Headers)
  ' Release the response object resources.
  streamRead.Close()
streamResponse.Close()
