Class: Mailscope::AssetsController

Inherits:
ApplicationController show all
Defined in:
app/controllers/mailscope/assets_controller.rb

Overview

Serves the engine's own CSS/JS from disk with an immutable cache header. This keeps API-only apps working without an asset pipeline, and avoids letter_opener_web's habit of inlining ~277 KB of vendor code into every single HTML response.
