It’s a lovely guide. Saves a lot of time vs reading the RFCs when you just want to debug a session state flow/log/packet capture.

The one thing I wish it had was better tracing of branch points like session resumption. It would make walking session state logs simpler.

I ran into this while trying to figure out if the open source Kubernetes nginx ingress supported session resumption on the upstream side (it doesn’t; a deficiency in the lua balancer). While the diversion into nginx source and other sundries was nice, I could have saved that time :)
