Message Pop-Up with option to continue OAM session before OAM Session timeout ends.

Version: OAM 11.1.2.3.X, WebGate 11.1.2.3.X,

In current OAM deployment, We have set idletimeout for each application on their respective App Domains. Functionality works as expected.

I was working with BlackBoard application to resolve an issue where user is taking an exam where the exam module makes backend XHR calls to app server when user selects an answer on the browser. This is good as long there is valid OAM Session. When OAM session timeouts/ends for some reason, then user will see application page is static with pop-up message with network related which is bad experience, but in background, OAM is doing its job of redirecting to login page for those backend calls which goes into loop as the App end code which they can handle
