The reason, why tntnet acts this way is, that the user application may throw
an exception or otherwise stop sending data keeping a open http-transaction.
And also tntnet needs to send a content-size-header prior to the body. This
can done only, when the complete body is known.
Still there is a direct mode, which can be enabled with reply.setDirectMode(),
which connects the reply.out() to the socket. But you need to fill in the
content-size header first and be very careful not to break http.
Luckily there is a standard module called [EMAIL PROTECTED] in tntnet, which
sends
static pages very efficiently. If you add e.g.
MapUrl /(.*.html) [EMAIL PROTECTED] /var/www/$1
you define a static webserver for html-pages.
Or you define
DocumentRoot /var/www
MapUrl .* [EMAIL PROTECTED]
which maps every url to the file in document root.
Tntnet takes also care not to break the document root with double dot attacks.
Unfortunately the standard components lack documentation. I need to write at
least some man pages for them.

I don't quite understand your problem. Can you please explain, what do you
want to protect.
