Preloader question

hi there,
i followed the tutorial on creating a preloader, works like a charm, however, i want it so it runs each time the site is loaded…
basically, weather the swf. is loaded into the cache or not.

below is the code:

bytes_loaded = Math.round(_root.getBytesLoaded());
bytes_total = Math.round(_root.getBytesTotal());
getPercent = bytes_loaded/bytes_total;
_root.loadBar._width = getPercent100;
loadTextTemp = Math.round(getPercent
80+70);
_root.loadText = loadTextTemp
_root.loadText._x += 1;
if (loadTextTemp > 88) {preloadertext.gotoAndPlay(2);
}
if (loadTextTemp > 110) {
_root.preloadertext.gotoAndPlay(“fadesweat”);
}
if (loadTextTemp > 130) {
_root.preloadertext.gotoAndPlay(“fademove”);
}
if (bytes_loaded == bytes_total) {
_root.gotoAndStop(3);
}

i was thinking maybe some way of setting Bytes_Loaded to 0 each time?
What you think?
