CURRENT CACHING LAYER

magnetFetch (src/lib/magnetFetch/magnetFetch.js)

Data is cached when the request is a GET and when any max-age is provided.

• GET is reading a server resource; other requests are for modification. The expectation for the app is that a modification should fail if it can't hit the server, and that it should always know when a modification fails. Therefore cached data is not appropriate for non GET requests.
• when max-age == 0 it means that the response is valid for offline mode,
