-Plug lives at the heart of Phoenix's HTTP layer, and Phoenix puts Plug front and center. We interact with plugs at every step of the connection lifecycle, and the core Phoenix components like Endpoints, Routers, and Controllers are all Just Plugs internally. Let's jump in and find out just what makes Plug so special.

 [Plug](https://github.com/elixir-lang/plug) is a specification for composable modules in between web applications. It is also an abstraction layer for connection adapters of different web servers. The basic idea of Plug is to unify the concept of a "connection" that we operate on. This differs from other HTTP middleware layers such as Rack, where the request and response are separated in the middleware stack.
