Symfony2从Before过滤器发送RedirectResponse

Question

I'm using Before Filter to detect what language is the application using (is it english or something else, for example) and then doing some stuff with it. After I've done that stuff, I would like to send a RedirectResponse to another Symfony route like this...

return new RedirectResponse(route_name)

but that doesn't work beacuse I'm not extending ContainerAware so the component that is getting the RedirectResponse object doesn't know what to do with it.

My question is, how to redirect from a before filter after I'm done with it?
