session is being expired autometically

example ur: http://www.domainname.com/temp/welcome/index

when I open it then refresh it.. if session is set then it will show Session working message. then remove the index from url and write about.. it will still show the session working message.

but when I'm clicking on the about hyperlink bellow the message "session working" then session is gone.

here below is the controller code:

PHP Code:

class Welcome extends CI_Controller {

    public function index()
    {
        if(isset($_SESSION['test_session'])){
            echo "session working";
        }else{
            $this->session->set_userdata('test_session', 'session set');
        }
        
        echo '<br><a href="'.base_url().'welcome/about'.'">about </a>';
    }
    
    public function about()
    {
        if(isset($_SESSION['test_session'])){
            echo "session working";
        }else{
            redirect('welcome/index', 'refresh');
        }
    }
}
