ASP.NET Web API异常筛选器

我正在尝试调用授权筛选器中的异常筛选器。调用异常筛选器后，它将记录来自授权筛选器的错误

Public Class AuthFilterAttribute
        Inherits AuthorizationFilterAttribute
        Public Overrides Sub OnAuthorization(ByVal actionContext As HttpActionContext)
            If actionContext.Request.RequestUri.Scheme <> Uri.UriSchemeHttps Then
                actionContext.Response = New HttpResponseMessage(System.Net.HttpStatusCode.Forbidden) With 
            {
                .ReasonPhrase = "HTTPS required"
            }           
            End If
            If actionContext.Response IsNot Nothing Then
                Throw New HttpResponseException(actionContext.Response) ''''' Calling the exception filter here '''
            End If
            MyBase.OnAuthorization(actionContext)
        End Sub
    End Class

Public Overrides Sub OnException(ByVal filterContext As HttpActionExecutedContext)
            If filterContext IsNot Nothing Then               
              ''' Logging my error here '''
              ''' What to send back the error code and message coming from authorizaton filter '''
            End If
        End Sub
