I'm trying to return a permanent (301) redirect response from a event subscriber hooked into the kernel events in Synfony PHP.

My subscriber is as follow:

use SymfonyComponentEventDispatcherEventSubscriberInterface;
use SymfonyComponentHttpKernelEventGetResponseEvent;
use SymfonyComponentHttpKernelKernelEvents;

use SymfonyComponentHttpFoundationRedirectResponse;

class KernelSubscriber implements EventSubscriberInterface 

 public function __construct() 

 // some stuff here but not relevant for this example
 

 public static function getSubscribedEvents(): array 

 return [ KernelEvents::REQUEST => 'onRequest' ];
 

 public function onRequest(GetResponseEvent $event): void 

 // if conditions met
 // 301 redirect to some internal or external URL

 if(!$event->isMasterRequest()) return;
 

If this were a controller I would return $this->redirectToRoute('route') or something like that but returning from the onRequest method is in a much different context.

How can I return a response (a redirect, in particular) from this event subscriber?

Should be something like:

$event->setResponse(new RedirectResponse($route));
