What this post added

This post details the fundamental concepts of building a web application from scratch using core Ruby libraries, covering network protocols (TCP and HTTP), persistent data stores, and the web server interface (Rack). It then demonstrates how these concepts are abstracted and implemented by Rails libraries like Action Controller, Action Dispatch, Active Record, and Action View, providing a comparative analysis of building with and without Rails.
