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());
