发送重定向不会更改浏览器中的 URL

Question

I am using Spring MVC. I do the following steps

1. Login into my application
2. delete browser cookies and cache
3. do a refresh

When I delete browser cookies and do a refresh it redirects me to the login page. But this login page is opened in the response of the API (in developers console) and not the actual browser.

I want to open the login page in the browser, how do I do that ?

   /**
 * Handles requests related to security of the application.
 */
@Controller
public class SecurityController {

    @Resource(name = "syncService")
    private SyncService syncService;

    @RequestMapping(value = "/login", method = RequestMethod.GET)
    public String login(ModelMap model , HttpServletResponse res) { 
        res.setHeader("URL", "Login");
        return "login";
    }

    @RequestMapping(value = "/403", method = RequestMethod.GET)
    public String acd(ModelMap model) {
        return "403";
    }

    @RequestMapping(value = "/next", method = RequestMethod.GET)
    public String next(ModelMap model) {
        return "next";
    }

    @RequestMapping(value = "/logout", method = RequestMethod.GET)
    public String logout(ModelMap model, HttpServletRequest request) {
        HttpSession session = request.getSession();
        session.invalidate();
        /* model.addAttribute("mess","you have been logged out"); */
        return "login";
    }

    @RequestMapping(value = "/accessdenied", method = RequestMethod.GET)
    public String loginerror(ModelMap model) {
        model.addAttribute("error", "true");
        return "denied";
    }

}
