1. Customize the error templates of the different error pages (explained below);

2. Replace the default exception controller ``TwigBundle:Exception:show``

2. Replace the default exception controller ``twig.controller.exception:showAction``

with your own controller and handle it however you want (see

:ref:`exception_controller in the Twig reference<config-twig-exception-controller>`);

:ref:`exception_controller in the Twig reference<config-twig-exception-controller>`).

The default exception controller is registered as a service - the actual

class is ``Symfony\Bundle\TwigBundle\Controller\ExceptionController``.
