1、直接Redirect后加 Controller/Action

Response.Redirect("/User/Edit");

return Redirect("/User/Edit");  

return RedirectToAction("about","Home");

Response.Redirect("/User/Edit");     

2、直接return后加 Controller/Action

return Redirect("/User/Edit");             

3、RedirectToAction方法，直接跳到一个action

return RedirectToAction("edit");

4、跳转的页并不在该Controller中  

return RedirectToAction("about","Home"); 

5. redirect跳转

String url = "redirect:/test.do";

ModelAndView mav = new ModelAndView(url);
