#asset_hosts=(host) ⇒ Object

Set the asset hosts for this app. It supports the following format:

  • plain string: the string literal will be considered as the asset hosts (e.g. ‘assets.foo.com’)

  • formatted string: to support asset host distribution (e.g. ‘asset%d.foo.com’)

  • a proc object: to support custom asset hosts generation (e.g. Proc.new { |source| ‘assets.foo.com’ }

The max number of distribution can be set from configatron.mack.assets.max_distribution. The default value is 4
