title: How to download and store images to not be cleared by device later?
body: <p>I have an application which downloads its product data(descipttions and images) from server and stores them localy to be available offline. For product images I'm using forge.file.cacheURL which works great but on my iPAD, this cache is being cleared during the day when I work with another apps. This causes my application to have only descipription texts available without images and user must connect to internet and synchronize again what is quite annoying. Is there a better way how to implement this scenario? </p>
