How to fix 400 error on POST request in yii?

Question

Yii

When a POST request occurs, an error 400 occurs.
The whole problem is that when the site has a redirect from / to /ru/
But the request is made to the address: test.ru/ru/page
If you send a regular GET, then everything is fine.
And if POST then 400.
Who faced and how to fix it?
Yii 1.1.16

Defined the problem. I have every POST requires CSRF.
What do you think is the right way to disable requiring CSRF on POST?
Solution:
Make a white list of servers from which you can receive POST without CSRF.
Make a class, inherit CHttpRequest, specify the path to it in the config, and override validateCsrfToken.
I got it like this:

public function validateCsrfToken($event){
        $request = Yii::app()->request;
        if(in_array($_SERVER['REMOTE_ADDR'], $request->whiteListIP)){
            $request->enableCsrfValidation=false;
            return;
        }
        parent::validateCsrfToken($event);
    }
