Understanding the Request Cycle in Phoenix Applications

The article dives into the process that occurs when a user inputs a Phoenix URL into their browser. It begins with a standard DNS resolution and HTTP request, then outlines how the Phoenix framework leverages a `%Plug.Conn` struct to manage these requests. Arrowsmith emphasizes the roles of components like the Endpoint, Router, and various plugs as the request goes through them, ultimately leading to the controller actions producing a response. The article sets the stage for more complex scenarios involving LiveView, indicating that the follow-up will cover how those interactions differ from traditional HTTP responses.
