configure_asset_host

🌐 Configure a Custom asset_host for CDNs​

Offload static assets to a CDN by setting config.action_controller.asset_host in your environment config. This speeds up asset delivery and leverages edge caching. Ensure you include the proper protocol or use protocol-relative URLs for flexibility.

# config/environments/production.rb
Rails.application.configure do
  config.action_controller.asset_host = 'https://cdn.example.com'
  # or protocol-relative
  # config.action_controller.asset_host = '//cdn.example.com'
end
