Except that there is the concept of buffered and unbuffered output. I am new
to servlets from the Perl CGI world where you must explicity unbuffer your
CGI output to get the behavior you are looking for. If not, the browser gets
all script output when you finish. This works for HTML as plain text
content. I'd have to think it can be done with servlets.
