Two things: 1) It's not a Perl issue. 2) What happens at the
client side is up to the client. That's how the Web was
designed. You tell the client it's a Word document, and the
client (whether or not directly directed by the user) decides
whether to display it in a plugin, display it using an external program, save it to disk, send it to the printer,
reject it or whatever it fancies to do. Why should the server
care?
