Hi, I have a question regarding the proxy cache plugin. In nginx there is a way for me to do background validation of cache and serve stale response until the cache is refreshed in the background using the following:
proxy_cache_use_stale error timeout invalid_header updating http_500 http_502 http_504; proxy_cache_background_update on; proxy_cache_revalidate on; I see that in apisix proxy cache plugin similar directives do not exist. Since APISIX is based on nginx, is there a way to achieve the same behavior with APISIX proxy cache? Basically I'm okay with serving STALE content from cache for a few seconds when the cache is being revalidated in the background. This helps me in controlling the number of requests I send to upstream when the cache just expired and prevents upstream from getting overwhelmed. Thanks, Karthik
