@coobic you are right, have added ->send(), thanks!

@r3verser so how do we use this, tehcnically, is there any manuals?
I'm using Yii2 advanced template.
thanks

@r3verser I like this, thank you. Is there a license? I see some people do this for gists: https://gist.github.com/martinbuberl/c0de29e623a1e34d1cda7e817d18bafe

Hi! I have updated gist to MIT license, thanks!

Nice behavior, thank you!

to make this work with parameter urls I've changed the beforeAction as following:

$requestUrl = strtok(\Yii::$app->getRequest()->url, '?');

    if (\Yii::$app->getUser()->isGuest &&
        \Yii::$app->getRequest()->url !== Url::to($this->redirectUri) &&
        !in_array($requestUrl, $this->allowedUrls)
    ) {
        \Yii::$app->getResponse()->redirect($this->redirectUri)->send();
        exit(0);          
    }
