Hi Bear, would you mind elaborating a bit more on this. I have seen this functionality in one of our internal portals, where some files are uploaded. But the message "File being processed" is something displayed on a another small browser window, which is not the same browser the original request is sent. But again, how is this periodic notification happening in one single request/response cycle.
