Still remaining question

How to detect session timeout while working in client?

One approach might be to periodically 'ping' the server in the background where the 'period' is less than the session timeout period set on server. from SO

The basic example:

setInterval(function(){
   $.get('/ImStillAlive.action');
}, 840000); // 14 mins * 60 * 1000

With basic check for typing activity:

$(function(){
    var lastUpdate = 0;
    var checkInterval = setInterval(function(){
       if(Date().getTime() - lastUpdate > 840000){
           clearInterval(checkInterval);
       }else{   
            $.get('/ImStillAlive.action');
       }
    }, 840000); // 14 mins * 60 * 1000

    $(document).keydown(function(){
         lastUpdate = new Date().getTime();
    });
});

Some opinion on rest and filter
