Never saw /cgi-bin/ in a form URL? Or the occasional xycorp_isapi.dll? :)
I remember using server push, and the CGI interface was a hell of a lot simpler than the 8000 levels of abstraction my Typescript Angular apps going through before they hit the wire.
The worst part is that the majority of the added complexity is useless. Instead of replacing the bad parts of HTTP, HTML, JS, and CSS we just build more shit on top of it. This requires more hacks and just up the complexity level even more.
