Session is not Expired in Vaadin

Im in the Middle of Developing WebApplication Using Vaadin and Spring. I Used AbstractJavaScriptComponent and Using setInterval() im getting data from the backend and display the data Real Time.

My Question is The Requests are act as User Request Request and Session is not timeout because Vaadin Received it as User Interaction.

Is there anyway to ignore the javascript Connection and activate session timeout according to Users UI Interactions.
