auto logout idle timeout using jquery php

Question

I searched and find some examples to set idle timeout using jquery.

1 - Idle Timeout By Eric Hynds DEMO

2 - Idle Timer By paulirish

3 - Fire Event When User is Idle / DEMO HERE

4 - detect user is active or idle on web page

5 - Comet Long Polling with PHP and jQuery

6 - detacting idle timeout javascript

... And several other similar examples

Between these examples number 1 is better for i need because i need to auto logout user with any confirm alert after X minutes (logout.php or any url). but this method Not suitable for server. problem is : this jquery code send ping to any url : keepAlive.php in loop/pooling for request OK text . see firebug screen :

how to fix this ? So, other examples only printed Idle/No Idle and not work with alert confirm and auto logout ( logout.php or any url ) now really better way to choose idle timeout using jquery/Php ?

Thanks

Answer 1

I use a meta refresh element in the head section to auto-direct users to the logout page after X number of seconds. Below will automatically send a user to the logout page after 20 minutes of staying on the same page:

<meta http-equiv="refresh" content = "1200; url=http://www.site.com/user/logout">

This works, is (mostly) supported cross-browser, does not rely on JavaScript being enabled and is pretty easy to implement.

If your site has users that stay on the same page for extended periods of time (with interaction taking place through JS, for instance), this solution will not work for you. It also does not allow any JS code to be run before redirection takes place.
