| 5 | // | |
| 6 | // After a set amount of time, a dialog is shown to the user with the option | |
| 7 | // to either log out now, or stay connected. If log out now is selected, | |
| 8 | // the page is redirected to a logout URL. If stay connected is selected, | |
| 9 | // a keep-alive URL is requested through AJAX. If no options is selected | |
| 10 | // after another set amount of time, the page is automatically redirected | |
| 11 | // to a timeout URL. | |
| 12 | // | |
| 13 | // | |
