Hi guys!
We currently use rack-cache in production and we are quite happy with it.
We discovered the stale_while_revalidate
flag for expires_in
in rails (https://api.rubyonrails.org/classes/ActionController/ConditionalGet.html#method-i-expires_in).
Is there any chance rack-cache could support something like this?
Returning the cache hit, but also forwarding the request to the rails app for revalidation.
Thanks in advance,
best regards,
Lukas

sounds reasonable ... PR welcome ... just make sure it does not add overhead for the default usecase :)
