use cache-control headers but allow cache for stale_on_error

[hmoffatt]

I've enabled cache_control=True on my session to respect the remote caching headers, but I also want to use stale_if_error. However when I fetch a remote URL that returns cache-control: no-cache, then it seems the response is not stored in the cache so stale_if_error can't work.

Is there any way to make these work together?
