app\resources\twigbundle\views\exception\error404.html.twing 

but want redirect user particular page. how can that?

you want create event listener listens kernel.exception event kernel dispatches when encounters exception.

then, check inside listener if exception instance of notfoundhttpexception, , if is, redirect page of choice.

here's exemple:

<?php // src/acme/demobundle/eventlistener/acmeexceptionlistener.php namespace acme\demobundle\eventlistener;  use symfony\component\httpkernel\event\getresponseforexceptionevent; use symfony\component\httpfoundation\redirectresponse; use symfony\component\httpkernel\exception\notfoundhttpexception;  class acmeexceptionlistener {     public function onkernelexception(getresponseforexceptionevent $event)     {         // exception object received event         $exception = $event->getexception();          if ($event->getexception() instanceof notfoundhttpexception) {             $response = new redirectresponse($url);             $event->setresponse($response);         }     } } 

obviously, you'll need register event listener. service, need register usual.

# app/config/config.yml services:     kernel.listener.your_listener_name:         class: acme\demobundle\eventlistener\acmeexceptionlistener         tags:             - { name: kernel.event_listener, event: kernel.exception, method: onkernelexception }
