Exactly, that's what it should do.

Your settings seems to be fine, so I see several possible answers:
- Ivy implementation is buggy and doesn't work in your case
- you use a dynamic revision without a long enough TTL
- Ivy doesn't find the cached files on disk for any reason

To clear out what's the exact problem, you need to check Ivy debug log which
should tell what it does with the cache. Post relevant section here if the
logs isn't understandable.
