I have the following code. I want to access booleanValueObj on nextPage.jsp. How is this done? The object is not always available to nextPage() method on every request, so a requestParam seems like it's not appropriate.

```
@RequestMapping(method=RequestMethod.POST)
public ModelAndView sendEmail()
{
    ModelAndView modelAndView = new ModelAndView();
    modelAndView.addObject(booleanValueObj, true);
    modelAndView.setViewName("redirect: /nextPageClass");
    return modelAndView;
}

@RequestMapping("/nextPageClass")
public class NextPageController 
{
    @RequestMapping(method = RequestMethod.GET)
    public ModelAndView nextPage() 
    {
        ModelAndView modelAndView = new ModelAndView("/nextPage");
        return modelAndView;
    }
}

```
