While I’ve never explicitly investigated this, the background session architecture, where the actual networking is done inside a system process, isn’t compatible with custom caching. Note that the ‘will cache response’ delegate callback takes a data task, and data tasks have only limited support in background sessions. Specifically, you can run a data task in a background session but it will fail if your app gets suspended [1]. Honestly, it’s quite rare to use a data task in a background session. Which brings me to: > I have a need to make several requests for (small) resources … Background sessions are optimised for a small number of large requests, making me suspect you’d be better off using a standard session. Why are you using a background session here?

In the original iOS 7 implementation, data tasks were simply not supported in background sessions. _______________________________________________ Do not post admin requests to the list.
