Yii2：如何在多站点用例中避免400个错误请求？

Question

I try to use one copy of Yii2 as multisite engine (one CMS, several domain-depended configs). But when I send some ActiveForm in a controller action, I see Bad Request 400. When I add _csrf field in simple HTML form and try to send it in an action, it works fine. How can I resolve it?

Here is a solution: I just name session with unique string for every domain. This is done by editing domain-depended configs.

return [
    'components' => [
        ...
        'session' => [
            'name' => 'domain_name_session',
        ],
        ...
    ],
];
