Abstract:

Methods and computer-readable media are provided for refreshing a page validation token. In response to a request for a form from a client, a server responds with the requested form, a page validation token, and a page token refresh program. The client executes the page token refresh program in response to a request to post the contents of the form to the server computer. The page token refresh program determines whether a preset period of time has elapsed since server computer generated the page validation token. If the period of time has not elapsed, the form is posted to the server with the page validation token and processed by the server computer. If the page timeout has elapsed, the page token refresh program refreshes the page validation token prior to posting the form by requesting an updated page validation token from the server.
