Even if this request is very lightweight on the server side, you shouldn\'t set the interval shorter as necessary because unnecessary short intervals, together with a large amount of concurrent active users, might generate perceivable additional load on your server. For normal Moodle setups, the default setting should be fine.<br>
 The interval is best set to half of the session timeout configured on the {$a->page} configuration page (currently set to {$a->minutes} minutes). Example: If the session timeout is set to 120 minutes, set the keepalive time to 60 minutes. The users\' browsers will then perform the first keepalive request 60 minutes after the page load which is still plenty of time before the session normally expires.';
