Symfony2重定向操作显示中间页面

Question

I've been using the following method for redirecting users from a page to another whenever they have successfully achieved something in the lines of a CRUD action;

return $this->redirect($this->generateUrl('_my_route'));

This, normally goes well. The user finishes the action, and gets redirected without any problems to the following page. But now I've got an action that does it differently without no apparent reason. It finished my request in the controller. It hits the above redirect statement and it shows me the following intermediate page;

Redirecting to /my/route/somewhere/on/the/site/.

And after showing this to me, it actually redirects me to the page I'm looking for after a short pause. Why is this happening? And what can I do to prevent it? I don't wanna see that I'm being redirected. And what's more frustrating; how is it possible that 19 redirects DONT do this, and this one does?

Thanks

This is because the headers have already been sent, somewhere. Check for any debug code - in fact, if you keep hitting esc on your keyboard to stop the javascript location change, and then inspect the source, you may be able to see what characters are being sent to the browser before your attempt your redirect.
