Alert user when their session is about to expire

Here is a quick and dirty trick to alert users on session timeout. This is not a perfect solution. But it will give reader an idea to work on...

Some facts before we start:

Session doesn't end

  • When the user closes his browser
  • When the user navigates away from your page
  • When user connection lost.

Session ends, when the server hasn't gotten a request from the user in a specific time (Session timeout value)....Permalink
