In the tests that I have done previously, the Java VM inherits the proxy
settings listed in the browser (at least this is what is supposed to
happen; sometimes this does not happen). So if the browser is
configured to use Privoxy and these setting are communicated correctly
to the Java VM, what is there to stop a Java applet from sending back
data through Privoxy?
