The session isn't really relevant here; creating a session has no impact on 
networking per se.  What matters is the tasks within that session.  And yes, 
you can start an upload task in a background session while the device is 
offline and it will then start transferring when the device comes back online.  
This should be possible on iOS 7 but, for best results, you want to use iOS 8.

Share and Enjoy
