Is there a way to just disable the cache completely? I have a display showing a programmatically generated image and it's caching and not displaying the updated image. If I stop and restart the player, it seems to pick it up. The content is local to the network, so performance isn't an issue.
I've tried sending all the expires and cache-control headers, and they seem to just be ignored. I'd be OK with 60 seconds or so, but really, I'd rather just disable it completely for a specific presentation .
Perhaps convert the URL to a POST or something?
