In addition to the answer provided in the comments, you can also use RedirectAttributes, and addAttribute method if you want to append a parameter to URL upon redirect. This will also give you the addFlashAttribute that will store the attributes in the flash scope which will make it available to the redirected page. You can also return a simple string as the view name e.g. like 

public String internalLoadPage(RedirectAttributes redirectAttributes) throws Exception 
    {
      redirectAttributes.addAttribute("paramterKey", "parameter");
      redirectAttributes.addFlashAttribute("pageKey", "pageAttribute");
      return "redirect:/home";
    }

this assumes that the view suffix is configured in you view resolver configuration
