Sorry, don't mean to be condescending or dismissive. Just trying to get stuff done. To do that, I'll need that information.

I've only used caddy twice, but it worked for like 2 years without interruption both times.

I don't think you're being negative or whatever and I also think the other person has an idea of what they want to know but not how to explain it.

Do they want connection handling metrics? SSL terminations? Caching performance?

Also, not at you but a general laugh, "the reverse proxy isn't the bottleneck ever" is funny because prior to haproxy, getting gigabit throughput to a backend was considered extreme engineering.

Now I can load balance and ssl terminate a gigabit with like 5 raspberry pi and an old Intel box to load balance and cache.
