Custom Application class which tries to redirect to one of specified routes before handling request.

It's useful if you moved website and forgot to set redirects properly and receiving many 404 Not Found errors.

Redirects go through standard \yii\helpers\Url::to() function, so they'll be 302 Found redirects.

Using Composer:

composer require rekurzia/yii2-redirect

Change your entry script (index.php) to use this class:

(new Rekurzia\redirect\Application($config))->run();

And add new routes through redirectRoutes option:

$config['redirectRoutes'] = [
    'some/route' => ['/site/index'],
    'another/route' => ['/site/index', 'page' => 'another'],
    'some/route?a=b&c=d' => ['/site/index', 'page' => 'abcd'],
    'outside/route' => 'http://www.yiiframework.com',
];
