Stale while revalidate support

[SGudbrandsson]

Hi,

I'm very interested in this proxy, it's very interesting for scalability in microservices.

Are there any plans to support Stale-while-revalidate to improve response time after cache entries expire?

Hello there! That could be a nice idea, definitely. If implemented, I'd say this would be an opt-in feature disabled by default in the configuration, as in Crisp's use case (for which Bloom was initially built), this would result in erratic behavior for the end user due to our messaging use-case.

Thank you!

Tagging issue for implementation.
