For a single JVM this is a nice way to handle multipel submits. But then a solution should never be limited to one JVM and if it has problems when multiple JVM;s come into the picture then it should re-thought upon. I would rather not go for such a solution even though it is a good solution for a single JVM.

Yes - of course it would. The solution is only for one JVM. You will need another approach for a clustered environment.

On each of these servers session object will be replicated. This means that the same request can go more than once. Shouldn't this solution fail then? ~madhav On 6/21/06, Paul Benedict wrote: > > I've read many different techniques to stopping double submits, but one > technique unfamiliar to me was described inside the Spring Framework. > > > http://www.springframework.org/docs/api/org/springframework/web/util/HttpSessionMutexListener.html > > It did not occur to me to lock the session to make sure that, within a > user's dialog with the server, only one request from a session makes it > through.
