You can't control if a user opens your applet/page once, 2x, 3x, etc.,
nor whether he opens those in new tabs or new windows. You cannot
redirect a user's request for a page/applet to a specific window or tab
in his browser because the browser won't tell about the existence of
such things.

However! If the user has his browser's cache enabled (and configured a
certain way) it is certainly possible (perhaps likely, but I'm not
willing to go that far) that the request for your page/applet will be
drawn from the user's local cache and not downloaded again from your
server. But you have no real control over that. Nor should you.
