avoid session timeout when user is active FR#1529

For review.
Please have a look if this workaround will work to avoid the session timeout. I have a timer on the frontend and that reset when any browser activity occur. Five seconds ahead of when a time out is supposed to occur, the script update the backed with the last time when user was active on the browser.
Suggest if I can do any modifications to make it better.
