/*
 *
 *  On Netscape Navigator 2.0, an applet can only make a connection
 *  to the computer that it came from.   This is either the http
 *  server named in the applet's URL, or the server named in the URL
 *  given in the applet's CODEBASE parameter. 
 *  
 *  Attempting to connect to any other host on the internet should
 *  raise a security exception. 
 *
 *  By default, the same holds for appletviewer.   If you place 
 *  appletviewer in "unrestricted" browse mode, then applets can
 *  make arbitrary connections.   For this reason, it is strongly
 *  suggested that you do not use appletviewer in "unrestricted"
 *  mode if you use it to load foreign applets.
