[ad_1]
I run a decently large Multisite (Using domains — not subdomains or folders) with 12 total servers (3 each for NGINX, Storage, DB and LB) and I have redis installed on the NGINX servers running in a cluster. All nodes are in the cluster.
My question is, do I need both NGINX Helper and Redis Cache? I’m finding when my users make an update, they can’t see it on the front end for quite some time. I thought the plugin cleared out the cache of any page that has recently been published.
Am I missing something?
