        ' The ContentLength and ContentType received as headers in the response object are also exposed as properties. 
        ' These provide information about the length and type of the entity body in the response.
        Console.WriteLine(ControlChars.Cr + "Content length :{0}, Content Type : {1}", myFileWebResponse.ContentLength, myFileWebResponse.ContentType)
        myFileWebResponse.Close()
    Catch e As WebException
        Console.WriteLine(ControlChars.Lf + ControlChars.Cr + "The Reason for failure is : {0}", e.Status)
