If you're using an Ajax form, refresh the page using JS. Specify what exactly your form does if you need more information.
<script>
var time = new Date().getTime();
var refreshTime = 600*1000;
$(document).bind("blur focus focusin focusout load resize scroll unload click dblclick mousedown mouseup mousemove mouseover mouseout mouseenter mouseleave change select submit keydown keypress keyup error hover change", function(e) {
time = new Date().getTime(); });
function refresh()
{
if(new Date().getTime() - time >= refreshTime)
window.location.reload(true);
else
setTimeout(refresh, refreshTime);
}
setTimeout(refresh, refreshTime);
</script>
