I don't think caching would be an issue(I have a similar process and I haven't seen it come up yet), because the Flash player isn't going to be wasting memory on caching unused data since it uses so much memory already. I could be wrong though in that assumption and it simply hasn't been a problem yet.
That being said, if you did run in to that problem you can simply append the timestamp or any random characters to prevent it from being cached.
