When a S3 client sends a GET Object with a range header, 206 http code is returned indicating success, however the call of the object layer's GetObject() inside the handler can return an error and will lead to writing an XML error message, which is obviously wrong since we already sent 206 http code. So in the case, we just stop sending data to the S3 client, this latter can still detect if there is no error when comparing received data with Content-Length header in the Get Object response.
