Tom, there may be some application, where such behavior is expensive, i.e. hit the 'acknowledge credit card charge' button twice. The worker servlet would have the requests first, so it has to intercept the second. As the out stream of the first is gone in the view of the browser, you would need clever logic. I.e. rollback the transaction of the first and execute the second as if nothing special happened.
