Public Overridable ReadOnly Property IsMutuallyAuthenticated As Boolean

    ' Create a new HttpWebRequest object for the specified resource.
    Dim request As WebRequest = CType(WebRequest.Create(resource), WebRequest)
    ' Request mutual authentication.
    request.AuthenticationLevel = AuthenticationLevel.MutualAuthRequested
    ' Supply client credentials.
    request.Credentials = CredentialCache.DefaultCredentials
    Dim response As HttpWebResponse = CType(request.GetResponse(), HttpWebResponse)
    ' Determine whether mutual authentication was used.
    Console.WriteLine("Is mutually authenticated? {0}", response.IsMutuallyAuthenticated)
    ' Read and display the response.
    Dim streamResponse As Stream = response.GetResponseStream()
    Dim streamRead As New StreamReader(streamResponse)
    Dim responseString As String = streamRead.ReadToEnd()
    ' Close the stream objects.
    ' Release the HttpWebResponse.
