MSIE will attempt to cache the old data, so you either have to specify
the header parameters in your data server to tell MSIE not to cache the
data, or you could add a bogus parameter to the end of the URL so that
MSIE thinks that it's a different URL and doesn't serve the old data.
var url2 = url + "?bogus="+(new Date()).getTime()
GDownloadUrl(url2, function(data) {
...
