Flash Slideshow and XML Cache

programming flash
1

Hi all,

I have altered the XML Slideshow from the tutorial on this site. I moved the interval to the XML file and other properties so that the swf file doesnt have to be touched to make updates. I have just run into the problem where my webserver is reloading the xml file, but cache-ing the images, so when an image is updated, it loads the cached version. Is there a way in the script to stop it from doing so and load a fresh version of the image everytime?

Here is my code:

//-----------------------
function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
image = [];
description = [];
url = [];
delay = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {
image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
description* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue; 
url* = xmlNode.childNodes*.childNodes[2].firstChild.nodeValue;
delay* = xmlNode.childNodes*.childNodes[3].firstChild.nodeValue;
}

firstImage();
} else {
content = "file not loaded!";
}
}
my_Date = new Date();
xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
xmlData.load("http://web6.dlife.com/dLife/do/ShowContent/flash_feature/images.xml?"+my_Date.getUTCSeconds());
