title: Stop browser scripts caching in GWT App
body: <p>I have a GWT app deployed onto our client's machines. As an ongoing
  development alongside, we have to release new improved versions of the
  application fron time to time. Everytime we release a new version we
  often run into the problem where the client's browser has cached the
  old scripts scriptsand for a while it behaves strangly as the data it
  is trying to work with is not quite compatible with it. What is the
  best way to overcome this problem. Currently I have to tell the users
  to clear their browser's cache for a new release but it would be nice
  they don't have to do this. </p>
