Calling a reverse HTTP proxy a Layer 7 proxy is misleading? Why?
Probably because OSI never materialized IRL and today they are all mixed up left and right and not how we “designed” and “imagined” it 50 years ago
I think it's only misleading in that the only L7 protocol it supports is HTTP. It's not a huge deal, but when I work with other proxies if I see L7, I assume multiple application protocols.
