php - Symfony2 throwing 404 inside kernel request event -

i may going wrong way, have onkernelrequest event setup picks current domain (multi site on single application), queries cache/db , stores in service use other controllers/services. works perfectly.

now if domain isn't found, i'd throw 404 error. i'd following in controller:

throw new notfoundhttpexception('not found!'); 

but results in uncaught exception in production, i'm assuming due priority of event (31).

php fatal error:  uncaught exception 'symfony\component\httpkernel\exception\notfoundhttpexception' message 'not found!' 

my current code (with logic removed clarity), note use jmsdiextrabundle configure services.

/**  * @service  */ class currentdomainlistener {     /**      * @observe("kernel.request", priority=31)      */     public function onkernelrequest(getresponseevent $event)     {         // find domain in cache/database...          if (!$domain) {             throw new notfoundhttpexception('not found!');         }          // store domain in service...     } } 

my question best way display 404 error when domain doesn't exist?

you return 404 response instead of throwing exception:

public function onkernelrequest(getresponseevent $event) {     // find domain in cache/database...      if (!$domain) {         $event->setresponse(new response('not found!', 404));     }      // store domain in service... }
