I just encountered a problem, that my app was released to the App Store, the update was already visible in the App Store, but the request to https://itunes.apple.com/lookup?bundleId=***&country=*** was still returning previous app version information.
After checking the server response, I realized that one of the response headers shows that the response is cached on the Apple server and that's the reason.
X-Cache: TCP_MEM_HIT from a104-85-249-20.deploy.akamaitechnologies.com (AkamaiGHost/11.1.3-49328623) (-)
Cache-Control: max-age=12989
.
The question is:
Can I safely use cache-busting solution to always get the latest results?
It could be done like: https://itunes.apple.com/lookup?bundleId=***&country=***&t=<current_timestamp>
I tested it and it works with the random timestamp, I always get not cached results.

Add a CommentTo add some information, setting URLRequest's cachePolicy to reloadIgnoringLocalAndRemoteCacheData does not invalidate the cache. Therefore, I ended up using the cache-busting method.
