Before filters with main page redirect when I call a controller with ajax

I created a filter which I added to the before list in the Config/Filters.php file, added some exceptions and everything works.

My application in several parts uses ajax to load content into the page, for example lists of records, or send data from forms.
In these cases the filter continues to work but the redirect is not done on the main page, but in the block where the content is loaded via ajax.
This all makes sense, because I call that controller and that controller is affected by the filter rules.

Is there a way to redirect the main page and not the ajax block?

Code example? Where redirect filter

My filter

PHP Code:

namespace App\Filters;

use CodeIgniter\Filters\FilterInterface;
use CodeIgniter\HTTP\RequestInterface;
use CodeIgniter\HTTP\ResponseInterface;

class Is_logged implements FilterInterface
{
    public function before(RequestInterface $request, $arguments = null)
    {
        $model = model('App\Models\Utility\Check');


        if (!$model->my_check()) : // return true or false

            return redirect()->to('/');

        endif;
    }


    public function after(RequestInterface $request, ResponseInterface $response, $arguments = null)
    {
    }
} 


As said, it works, the problem is in the ajax calls, I know that the behavior is logical, I would need to redirect the whole page and not just the block where ajax writes

Do you want an unauthorized user to be redirected to the main page when requesting Ajax?
then you need to determine that the request is from XHR and return some status or link. In JS function check "url = redirect or html = paste on page" condition

Let me explain, I'm migrating a big application from CI3 to CI4, I'm practically done, I'm trying to fix some things that can still be improved with the new features of CI4.
One of these are filters and the use of before and after.
I already have the same control managed by javascript, but I wanted to take advantage of the filters also avoiding extra http calls.
The behavior must exist both on "normal" calls, and in ajax calls.
If there's no way to tell php/CI to redirect the entire page and not just the ajax-handled portion, I'll stick with the current pure javascript version.
Passing a parameter would also be feasible, but some calls only return html and it would be problematic to modify the whole structure, thanks anyway for the advice, but at this point I think I'll stay with the javascript version
