ActionScript 2.0 :: Preventing Swf From Reloading On Page Refresh?

Flash CS5, CS4
Actionscript 2

What I want the SWF to do is play from the beginning when someone hits the index.php file and gotoAndStop(234) when someone goes to a sub-page (like contact.htm).What I did first was:

<CODE>
function checkSO() {
var SO = SharedObject.getLocal("siteSO");
if (SO.data.visitedAlready != undefined) {

[code]....

And that worked in the sense of no cookie-it loads and plays the swf from the beginning. If

there is a cookie it starts from frame 234.

As it sits now as long as the cookie exist in the TIF everytime they return to my page it will not play the opening animation it will just jump to then end even on the index.php.

Someone else suggested:
<CODE>
import flash.external.*;
var currentURL:String = String(ExternalInterface.call("window.location.hre f.toString"));

[code]....

I just don't know what string (I think) to put in the /** ...flush.. **/ part
