caching with action script

[tigomark]

Is there a way to write an action script that will make sure that caching is set to zero.

I handle caching in my php script

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");          // Date in the past
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); // always modified
header("Cache-Control: no-cache, must-revalidate");        // HTTP/1.1

however the flash player seems to not respect the caching script and thus the information outputed does not update.

var header:URLRequestHeader = new URLRequestHeader("pragma", "no-cache");
           var request:URLRequest = new URLRequest("URL");
           request.requestHeaders.push(header);

Ok so I put this code into my function

   private function resetForm():void{
        
		var header:URLRequestHeader = new URLRequestHeader("pragma", "no-cache");
        var request:URLRequest = new URLRequest("https://mysite.net/interface.php?action=showopen&operation=showassets&format=xml&opstatus=crit");
        request.requestHeaders.push(header);
        	
        tempXML.asset = tempXML.asset;
        }

And there is no change. My onclick event will reset hover over information and any clicked info but the form won't reset and any new iformation will not be displayed. Is there soemthing that I am missing?

also this is originally called once the state is changed at

<mx:XML id="tempXML" source="https://mysite.net/interface.php?action=showopen&amp;operation=showassets&amp;format=xml&amp;opstatus=defect" />
	
	<mx:TileList dataProvider="{tempXML.asset.fleet}" 
		width="344" backgroundColor="#000000" color="#ff0000" fontSize="27" borderColor="#000000" columnWidth="300" rowHeight="50" themeColor="#808080" fontWeight="bold" allowMultipleSelection="true"  id="tilelist1" height="0" y="202" x="178"/>
		<mx:XMLListCollection id="tempXMLList" source="{tempXML.asset}" />

i tried changing statuses from the original url to a different state just to make sure. still no updating

Ok this whole thing goes to the fact that I never reset the list in
the first place.

So what I need to do is take the list

private function resetForm():void{


tempXML.asset = false; //clear it I could also us tempXML.asset =
newXMLListCollection(tempXML.asset); either way it clears it
tempXML.asset = tempXML.asset; //redisplay it



}

This will definatley clear out the old list but now I need a way to
recall the same list from the

<mx:XML id="tempXML"
source="https://mysite.net/interface.php?action=showopen&amp;operation=showasset\
s&amp;format=xml&amp;opstatus=defect"
/>

and I'm not quite sure how to do this
