 * SocketAppender "appends" a logging event to a socket, configured
 * for a specific host and port number.  On the receiving side of
 * the socket can be a SocketReceiver object.  The SocketReceiver
 * object receives the logging event, and then "posts" it to the
 * log4j environment (LoggerRepository) on the receiving machine, to
 * be handled by the configured appenders, etc.  The various
 * settings in this environment (Logger levels, Appender filters &
 * thresholds) are applied to the received logging event.
 * <p/>
 * <p>Receivers can also be used to "import" log messages from other
 * logging packages into the log4j environment.
 * <p/>
 * <p>Receivers can be configured to post events to a given

 * <p>Subclasses of Receiver must implement the isActive(),
