Serve stale content from cache if origin responds with 5xx about cache-handler

[mholt]

@francislavoie Agreed -- and this feature should be pretty easy to implement. Caddy has a ResponseRecorder which can help the cache decide whether to respond or not.

I define stale content as content for which the cache-control max-age has already expired, but it is to be kept in the cache anyway and served as a fallback if the origin is unresponsive/responds with errors

[francislavoie]

@mholt I think this issue should be moved to https://github.com/caddyserver/cache-handler

@rrva are you still interested in this and/or willing to test an implementation?

[rrva]

@gc-ss Sorry, no interest has faded for the moment (not using caddy in this capacity right now).

Maybe we can take into count stale-if-error from Cache-Status - https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cache-Control

Should this issue be moved to https://github.com/darkweak/souin ?

[darkweak]

In the Souin codebase we support the stale-if-error directive
