How can you create a cookie after login?

We can create a hook for post login Action

in the action we can create cookie using HttpServletResponse

public class MyLoginPostAction extends Action {

    @Override
    public void run(HttpServletRequest request, HttpServletResponse response)
            throws ActionException {
      
      
       Cookie loginCookie= new Cookie("loginCountry", "DE");
        response.addCookie(loginCookie);
    }

}
