How to prevent the same?
Because it is not "refresh", it is "reload". Browser cannot refresh a page, but it can resend the request that generated this page. Thus, browser resends your last POST request which calls your DispatchAction. Your choices: * to use token. Browser will still resend a request, but you can check whether it is a resubmission, thus you can prevent calling your method. This will be more complex for DispatchAction, you need to check token before your handler is called. * to use redirection to your result page. See http://www.theserverside.com/articles/article.tss?l=RedirectAfterPost and http://www.theserverside.com/articles/article.tss?l=RedirectAfterPost2 for possible implementation.
