I guess I'm doing something similar, in that I'm auto-refreshing a very basic 2D graph which refers to an XML file on the same webserver. This XML file is updated every 10 seconds but even when the webpage is refreshed (with the standard HTML NO-CACHE tags etc), the data doesn't change to reflect the new settings/data in the XML file.
I'm using the embedded flash method on the webpage itself - so how can I insert code similar to the above to ensure it doesn't cache the XML data each time it auto-refeshes?
thanks!
