class DefaultController extends Controller

        $request = $this->get('request');
    	return new Response(var_dump($request->isXmlHttpRequest()));
    }
}

js script

$("#ajax").click(function(){
  $.ajax({
     	type: "GET",
     	url: "/app_dev.php/admin",
     	headers: {'X-Requested-With': 'XMLHttpRequest'},
     	success: function(msg){
      	 alert(msg);
     	},
     	error: function(msg){
     		console.log(msg);
     	},
 	});
});

Nothing extra is needed. The default setting shows everything. Take a screenshot with open the dev tab where the xmlhttp request left and so that the profiler can be seen
