code: public static LinkedBindingBuilder<Handler> bindLoggingHandler(final Binder binder)
      {
          final Multibinder<Handler> handlers = Multibinder.newSetBinder(binder, Handler.class, LOGGING_NAMED);
          return handlers.addBinding();
      }
docs: Bind a new handler into the jetty service. These handlers are bound after the servlet handler and will not see any requests before they
  have been handled. This is intended to bind logging, statistics etc. which want to operate on the results of a request to the server.
  
  Any handler intended to manage content or a part of the URI space should use {@link HttpServerHandlerBinder#bindHandler(Binder)}.
