Unblocking Apple App Store and Google Play Store

Hello Experts - I'm trying to figure out how to setup a whitelist which will only allow users to access the Apple App Store, Google Play Store, and one application for my company...nothing else.  I have it setup with a simple FIOS connection and D-Link consumer router which has a whitelist of allowed URLs.  Google play seems to work fine but the Apple store does not.  I allowed the apple.com domain but when I browse the store there are no pictures and the apps won't download.  Can anyone tell me if what I want to do is possible and if so what additional domains need to be whitelisted for the Apple store to work?
