[Chilli] Show a notification when a user's session is about to end

[Gergely Kiss]

Hi Jonas,

I don't use the latest release of CoovaChilli, so this method may not work
for versions newer than 1.2.2. But it worths a try...

Some time ago I created a slightly modified version of the JSON interface -
it was extremely easy to customize the code, even for me (I'm not a JS
expert).

This function should do the work:

var userNotified = false;

// Shows a notification if session timeout is about to expire
function timeoutNotification () {
   var notifyLimit = 600; // Set the notification limit here in seconds (10
minutes by default)
   var tSessionTime = parseInt ( chilliController.accounting.sessionTime ,
10 ) ;
   var tSessionTimeout = parseInt ( chilliController.session.sessionTimeout
, 10 ) ;
   var tRemaining = tSessionTimeout - tSessionTime;
   if ( tRemaining < notifyLimit && userNotified == false ) {
      alert('Your session is about to end in ' + Math.floor (tRemaining /
60) + ' minutes.');
      userNotified = true;
   }
}

These lines should be put to the top of chilliController.js. You also need
to actually call this function somewhere in the code, the best place would
be the "updateUI" function, which runs each time the timer specified in
chilliLibrary.js expires ("interval"):

function updateUI (cmd ) {
[...]

    if ( chilliController.clientState == 1 ) {
        if ( chilliController.statusURL ) {
       chilliController.statusWindow =
window.open(chilliController.statusURL, "");
    } else {
       showStatusPage();
*       // notifies user before the session times out
       timeoutNotification();*
       setDirtyFlag();
        }
    }

[...]
}

I've set the timeout to 5 seconds, so at most 5 seconds after the specified
notification limit, the warning message will be presented to the user.

I'm not able to test the code right now, but hopefully it's simple enough to
work out of the box...

The customized version of the JSON interface is also attached for you - you
just have to put the files into the "www" folder of your CoovaChilli
installation (generaly to /etc/chilli/www) and put your network name and
logo to "index.html" and "splash.html".


Regards,
Gergely
