We can see that in NGF 2.4.0 session persistence was made available for ip_hash in NGINX OSS and cookie-based sessionPersistence in NGINX Plus.
Is there an update to using cookie-based sessionPersistence in NGINX OSS?
This is in relation to our ingress-nginx migration for the annotation nginx.ingress.kubernetes.io/affinity: "cookie" and the multiple nginx.ingress.kubernetes.io/session-cookie-* annotations you use with it.
