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));
