My first thought would be to use localStorage (if available). I would then keep here the date/time of the last request (and so the session ends x minutes later).
I 'm not sure what you are using with Ajax but either you extend the session lifetime or you don't have the session available and more likely you do use it to store the last http query date/time? Or you would need to pass something to get this info from
the server side.
