Internet Explorer (actually other browsers as well) has a nasty habit
of caching xml data.
The quick and dirty way to avoid it (assuming you are using some
javascript to get the xml)
could be assigning a unique (or random) querystring to your request:
...
myLovelyAjaxObject.get("http://path.to.my.xml.file.xml?r="+Math.rand());
...
If you want to ensure that the querysting is unique you may generate
and ID for it server-side.
