AMCharts and CodeIgniter

[eluser]Unknown[/eluser]
I managed to figure out a makeshift solution. amCharts was adding a timestamp on a query string to prevent caching and they have a setting to turn this off. The caching is obviously undesirable so I just made my own makeshift version by routing an extra URI at the end and dropping the time(); function into it, so now it's /charts/data/CHARTID/TIMESTAMP.xml

Works like a charm
