Dear Mike:
As I know, you can use out.flush() in some place so that user can see some
contents while waiting for long time processing to be finished. I don't
think it's
necessary. But for out.close(), I think it's better to add it all the time.
The rule
is, when you open a stream, better to close it after using it.
Regards
Liwen
