We'll now explore the flow of a traditional HTTP request, analyzing each step of the process up to when a response is rendered.

Phoenix also uses this adapter to interact with the Cowboy web server. When a requests hits the server, this adapter handles it, creates a new conn (a %Plug.Conn{} struct), and calls the endpoint configured in your application. By default, the endpoint is called <name_of_your_app>.Endpoint. The endpoint is the boundary between the web server and our application code, so essentially the endpoint is the beginning of a request. Let's see the configuration ...
