Hi, I have followed the below link in order to set session flush when the browser is closed. [https://gluu.org/docs/ce/3.1.4/admin-guide/session/#how-can-we-force-the-user-to-log-out-if-the-browser-is-closed](http://) But after setting `sessionIdLifetime` to `-1` it is working with Firefox browser. But for Chrome Version 72.0.3626.121 GLUU session is still maintained even when the browser is closed and re-openned.
