Country Restrictions

  • Due to distribution licensing and tax laws, certain content may not be cache-able in certain countries. As of December, 2013, iTunes downloads are not cached in Brazil, Mexico, China, and Portugal, and iBooks downloads are not cached in Canada.
  • If the country a client is in, based on its IP address, is different from the country of the iTunes Store being used, iTunes downloads will not be cached. For example, an iPad user in San Francisco can download an app from the German iTunes Store, but will not be able to utilize the caching service.
