Hi All,
I could not frame a reasonable text for the subject of this post, so had to use that subject, as partly the question is related to file uploading.
But the actual question is,
During the file uploads, specially if the file that is being uploaded is really huge, we do get notification something like "File is being processed" or some sort of progress bar, etc etc.
Now how is this particular functionality handled. Is this handled at client side or at server side?
If client side, how would client ever know, if the request is still being processed, as Servlet would not have committed the response back.
If Servlet sends those notifications back to client, that means it has already commited a response and the request/response cycle is over.
This above scenario is possible, if some sort of Asynchronous mechanism is employed, If I'm not wrong. But, is this actually possible in synchronous world? if yes, any pointers.
Thanks
