I have configured Casale as my default campain for Burst. Utilizing the links provided to me by Casale. But, it now appears the Casale ads are being cached. The burst ads run fine, and do not cache. But whenever it default's to a Casale ad, it is cached! The same Casale image repeats itself continually. If I hard code the Casale code into my website, it does not cache.

Does Burst have any sort of Cache busting I can apply to the URL for default campains? Is this a common issue?
