Warning and redirect not working for this settings

[jdemovic]

Hi,
thanks for great plugin.
I have one problem due to requirement settings.
Settings are:
APP idle setting 900 seconds (15 min)
Plugin Warning idle settings before 300 seconds (5 min)
Keep Session Alive = 'YES'

Output: Warning and redirect never occur

there is response with parsing XML error

For example: If I use Another settings like APP: 120 seconds and Plugin warning 60 seconds everything works fine. ( or 150 seconds and 50 seconds etc. less AJAX requests for Keep Alive Session check).

If i turn off Keep Session Alive attribute - everything works as expected too.

Regards

J
