Filters:after appears to be ignored

From what I can gather, the other setting that will probably make a difference is $sessionExpiration, which a the commment in the framework has this to say about:  "Setting to 0 (zero) means expire when the browser is closed."

I always thought that meant the number of seconds regardless of the state of the browser...but I guess it actually means the number of seconds a session lasts AFTER the browser is closed. OR MAYBE NOT haha. But yeah, to zero it is. Maybe I can even remove my 

PHP Code:

Events::on('post_system', function () {
    if(isset($_SESSION))
        session_destroy();
}); 


with these alterations. Only time (with testing) will tell.

You can see things I made with codeigniter here: itart.pro its not overly impressive as I have very little time to learn.
