Java EE (Java Enterprise Edition) General Discussion

I am looking for suggestions on how others may be handling the saving of client information when issuing a "redirect" to another page.

We want to use a redirect to ensure that if a user happens to hit the reload/refresh button on their browser, that they don't re-execute an update transaction. At the same time, however,there may be "session" information that we still want to retain. Obviously, when issuing a rediect we are losing the HttpSession associated with that request.

What techniques are others doing to save "session-related" information when using a redirect?
