How do I disable the Symfony 2 profiler bar?

Question

It\'s not adding anything and it makes the page slower and I want it gone. Don\'t ask. There\'s little about the profiler on the website and nothing in the app config.

Answer 1

To still get output in /_profiler but without the toolbar, you can cheat:

$request->headers->add(array('X-Requested-With' => 'XMLHttpRequest'));

That's because in WebProfilerBundle/EventListener/WebDebugToolbarListener.php there's an explicit check for this before injecting the toolbar.
