BEFORE YOU POST, search the faq at <http://java.apache.org/faq/>
WHEN YOU POST, include all relevant version numbers, log files,
and configuration files. Don't make us guess your problem!!!
----------------------------------------------------------------
And I would like to add that I do properly close() the output stream at the
end of the doPost/doGet, and at that time I do get output, provided the
browser hasnt timed out on me, however, that is not what I want. I would
like to FLUSH midway in doPost and be able to see the results up to that
point, or not even the results, I just want the TITLE of the page
displayed. And out.flush() does not cut the mustard for this particular
purpose.
Please help.
Thank you in advance,
Martin
