Unfortunately, I don't think anything can be done about this. As you surmised, the response length is zero to indicate that there is no data (i.e. a null response). The isNone setting is used to indicate that no response at all was posted and really can't do double duty in this case. A zero-length data response is perfectly legitimate. -- You are receiving this because you are subscribed to this thread.
