title: How to have flash scope functionality in Spring 3.0?
body: <p>I have ControllerA which performs quite a heavy duty logic and displays the result in html, the same set of result is now need to be exported in a excel sheet. I don't this is done by heavy duty stuff in controllerB again to generate and put it in excel. </p>
  
  <p>Spring 3.1 have introduced Flash scope, like spring web flow but I don't think Spring 3.0 have such thing. 
  Considering I cannot migrate to Spring 3.1 just as of now, I'm just wondering what would be the best and simplest thing I can do to get the same effect.
  Should i go with some Custom scope? </p>
