Redirect to a different page from Library class in CI4 - serjik - 01-29-2025

I would like to make a redirect from Library class in CI4. It does not work. I am changing the code from CI3 to CI4 and after I read a lot of topics regarding redirect I could not find an example for my case.
In CI3 it was easy to use redirect():

PHP Code:
redirect(base_url($redirect_url), 'location', 301); 

I used these redirects and it does not work:

PHP Code:
return redirect()->to(base_url($redirect_url));
return redirect()->to($redirect_url); 

I am getting an error if I use redirect()->route():
The route for URL cannot be found.

PHP Code:
return redirect()->route($redirect_url,[], 301); 

This is not from Controller. I need a redirect to a different page from Library Class, which is located in APP\Libraries\LibraryFolder\LibraryClass.php

Please let me know if there is a way to make it work.

This works in a html view may work in a library not sure or tested.

PHP Code:
// Try to use a named route.                        |name
$routes->get('{locale}/blog', 'Blog::index', ['as' => 'blog']);

// then try the redirect
return redirect()->to('blog');

No, this redirect does not work from the Library class.
I tried to use header() and it works only with exit()

PHP Code:
header('Location: '. base_url($redirect_url));
exit(); 

I created, as a temporary solution, a function in helper:

PHP Code:
function redirect_to_page($page) {
    header('Location: '. $page);
    exit();
} 

I am using it in the library class:

PHP Code:
redirect_to_page(base_url($redirect_url)); 

It would be better to use CodeIgniter methods, but so far I could not find a solution.
