When a user is complete using a tool launched through LTI (and embedded in an iframe) we are developing, he can press an 'exit' button to close our application.
The code under that 'exit' button forwards the browser to the value specified in 'launch_presentation_url' along with our 'thank you for using our tool message'.
All that looks fine and works, but after the message is shown, the entire LMS closes out and brings the user back to the canvas login screen.
I would have thought the iframe would just go blank and the remaining UI stays intact.
Is the entire app supposed to log out when my LTI tool is terminated?
