Web application designers and programmers often face situations where a form submission must be protected against a rupture in the normal control flow sequence. This situation typically occurs when a user clicks more than once on a submit button before the response is sent back or when a client accesses a view by returning to a previously bookmarked page. Control flow sequence is particularly important to preserve when form submission involves transaction processing on the server.<\/p>\n
