Excuse me, but how will that keep the user from caching the document?
It still goes via HTTP to the user's browser and can be captured there.
No pragma can prevent the user from capturing the document, when the user
can turn off any pragma at his/her/its end - if not within the browser,
then through the use of a tiny Perl program that would serve as an HTTP
filter between the browser and the webserver. I use The Proxomitron
for such purposes, and it can do pretty much anything you can write a
rule for. So I don't see how the original poster's problem can be solved
by Perl. A client-side solution in Java may be possible...
