Stop caching of XML file for image gallery

I’m using an image gallery that reads data from an XML file (image, title & description) so that it is easily updatable. My problem is that the browser is caching the XML file and I don’t see the updates unless I empty the cache.

Because there is only 1 html file, I placed the lines in the file:

<meta http-equiv=“pragma” content=“no-cache”/>
<meta http-equiv=“expires” content=“0”/>
<meta http-equiv=“cache-control” content=“no-cache”/>

The main flash file loads another swf file - gallary, which in turn is calling the XML file, and it seems to be coming from the cache.

Any ideas to make sure the browser reads from the server everytime?
