Jonathan Hefner 7415b93580 Avoid ActionController on ActionMailer::Base load This refactor avoids unnecessarily loading `ActionController::Base` when loading `ActionMailer::Base`. Before: ``` $ bin/rails r 'Benchmark.memory { \|x\| x.report("load"){ ActionMailer::Base } }' Calculating ------------------------------------- load 10.013M memsize ( 1.372M retained) 78.341k objects ( 14.363k retained) 50.000 strings ( 50.000 retained) ``` After: ``` $ bin/rails r 'Benchmark.memory { \|x\| x.report("load"){ ActionMailer::Base } }' Calculating ------------------------------------- load 5.043M memsize ( 729.741k retained) 38.854k objects ( 7.809k retained) 50.000 strings ( 50.000 retained) ```		2022-05-20 11:57:34 -05:00

= Action Pack -- From request to response

Action Pack is a framework for handling and responding to web requests. It
provides mechanisms for *routing* (mapping request URLs to actions), defining
*controllers* that implement actions, and generating responses. In short, Action Pack
provides the controller layer in the MVC paradigm.

It consists of several modules:

* Action Dispatch, which parses information about the web request, handles
  routing as defined by the user, and does advanced processing related to HTTP
  such as MIME-type negotiation, decoding parameters in POST, PATCH, or PUT bodies,
  handling HTTP caching logic, cookies and sessions.

* Action Controller, which provides a base controller class that can be
  subclassed to implement filters and actions to handle requests. The result
  of an action is typically content generated from views.

With the Ruby on Rails framework, users only directly interface with the
Action Controller module. Necessary Action Dispatch functionality is activated
by default and Action View rendering is implicitly triggered by Action
Controller. However, these modules are designed to function on their own and
can be used outside of Rails.

You can read more about Action Pack in the {Action Controller Overview}[https://guides.rubyonrails.org/action_controller_overview.html] guide.
