/**
 * The RMISocketFactory is used by the RMI runtime in order to obtain
 * client and server sockets for RMI calls. The default implementation
 * of the socket factory performs a three-tiered approach to creating
 * client sockets. First, a direct socket connection to the remote VM
 * is attempted.  If that fails (due to a firewall), the runtime uses
 * HTTP with the explicit port number of the server.  If the firewall
 * does not allow this type of communication, then HTTP to a cgi-bin
 * script on the server is used to POST the RMI call.
 *
 * An application may set the source of sockets for RMI. In this case,
 * the application is responsible for offering up sockets that will
 * penetrate a firewall.
