EGOCache currently stores its data under APP_HOME/Documents/EGOCache which means the cache gets backed up by iTunes. Most of the time, this probably isn't what you want (as the data can easily be recreated) and probably only increases user backup times if your cache is quite big.
Apple recommends using the APP_HOME/Library/Caches folder as this is not backed up by iTunes but is persisted between application launches.
