Enhancement Proposal
Proposal to add https://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_cache_background_update support.
The change should be backward compatible.
It may require side changes due to this mention in the configuration:
Allows starting a background subrequest to update an expired cache item, while a stale cached response is returned to the client. Note that it is necessary to allow the usage of a stale cached response when it is being updated.
