In some situations this doesn't suffice. For example, when you call a
utility class to generate your page and that class decides it need to do
a redirect. There's no easy way for it to say "we're done here, no more
output".
Picture you're writing a class to detect if the client supports
cookies. In ASP, the utility could do the work without bothering the
programmer. How it works is first thing in your page, ask the utility
getCookieSupported(). If the utility doesn't know the answer, it does a
redirect (with a test cookie) to check and calls response.end. The ASP
caller never knows control was taken away. But the next time the client
visits the ASP page the getCookieSupported() call returns a valid true
or false. Snazzy, but not possible in JSP near as I can tell.
Seems a limitation of a stack-based language. Best you could do is set
a flag to have future response output ignored.

P.S. To the original poster, don't call System.exit(). That would be
asking the server to exit execution.
