I am using trusted authentication to embed tableau views into our custom application. The custom application has its own authentication and session management (eg - log off after inactivity of x hours). When a user does not provide any action for long period of time widget is redirecting to login page over and over again. So I need to refresh this page by hiting "F5" to get data from tableau. Is there any way to process it automatically?
While I have never done this, apparently it can be done using a Java script. Try searching for Java and auto-refreshing.
