Jsp page not redirecting to another jsp page

I know this question has already been answered but i have a specific issue, when i return a redirect from a controller to another controller which returns a view, the view is sent as a response. I'm not able to display this JSP page sent in the response. The preview of the response is exactly what i want to display in the window. I'm able to do this with help of Ajax but i want my controller to redirect to the page.

@RequestMapping(value="validate")
public String validate(String validateLogin){
    System.out.println("Validation begin");
    System.out.println(validateLogin);
    if(directoryService.validateUser(validateLogin)){
        return "redirect:welcome";
    }else{
        return "/index";
    }

redirects to

@RequestMapping(value="welcome")
public String justToRedirect(){
    if(CurrentUser.getUserType().equalsIgnoreCase("admin")){
        System.out.println("User type is Admin");
        return "/welcomeAdmin";
    }else if(CurrentUser.getUserType().equalsIgnoreCase("user")){
        System.out.println("User type is Client");
        return "/welcomeUser";
    }else{
        return "index";
    }
