I found two vizportal api: getSessionInfo & getServerSettingsUnauthenticated, they look like api to check session. But I can't find any document about them. Can you provide any document about vizportal api? thank you very much!
Even i am looking for a solution for this. i have set an idle timeout of 15 minutes. I tried to load a dummy chart every 14 minutes to extend the session. this seems to be working however, when i try to load a dummy chart to a div element whose size is 0, i see setPortsize() call being made. This re-renders the current chart as well.
Let me know if you found any solution for the same.
