Answer 1

Try disabling the cache with ajaxSetup

$.ajaxSetup ({
    // Disable caching of AJAX responses */
    cache: false
});

function updateComm() {  
 var url="commandSys.php";  
 jQuery("#theElement").load(url);  
}

setInterval(updateComm, 1000);

Alternatively, you can manually just append a +new Date to url so it appends a query string to prevent caching.

Alternatively, disable caching on the server-side.
