How to remove flash cache on a web site periodically

I'm using a flash rotating banner in my website which takes images and descriptions from an XML file.

I do changes to my XML very often... but in my local machine, the banner takes a day or two to get updated.

Although I can clear my local machine's cache, the problem still remains for other users who visit my web page..

is there a programmatic way in flash or in html to overcome this problem ? Maybe a server configuration? Please help me with this..

PS: below code works fine, but it clears out the cache completely... i need to clear XMl cache after a specific time period.. please help.

var timestamp:Date = new Date(); 
xmlData.load("/flash/images.xml?cachebuster=" + timestamp.getTime());

如果您想每天清除缓存，请使用以下命令：

var timestamp:Date = new Date(); 
xmlData.load("/flash/images.xml?cachebuster=" + timestamp.getMonth() + timestamp.getDate());

If you desperately need the XML to update continuously (like live-statistics) you can call the code each time your banner loops before populating your content.

In general, Sam's code is fine - often you don't need your flash to clear the XML after a time period - it only needs to clear each time the user views your banner.
