Inside Rails...
summary
Explains exactly how an HTTP request becomes a controller method: DNS → TCP/HTTP → web server → use and run in config.ru → Rack ENV hash → middleware chain → routes → Controller.action.call, with live demos of rackup and Rails.application.call proving it works. Shows how middleware implements redirects, compression, and how everything is a Rack app, how to list and remove Rails middleware, and how Skylight middleware collects traces (Skylight product partially written in Rust). Company notes seven people and is hiring.
