Experimental stale and immutable response directives #8

Closed AaronO closed 6 years ago

AaronO commented 6 years ago

Support parsing response directives with:
- immutable
- stale-if-error
- stale-while-revalidate

These directives are supported by some CDNs (e.g: Fastly) and can be useful in proxies.

Cool. Thank you for the PR.

Shouldn't immutable change the behavior of CachableResponse? As a first pass, just parsing it is great, but it points to actually doing the work in #1.
