gistfile1.rb

  # Full error reports are disabled and caching is turned on
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true

  # Disable Rails's static asset server (Apache or nginx will already do this)
  config.serve_static_assets = true
  config.static_cache_control = "public, max-age=31556926"

  # Compress JavaScripts and CSS
  config.assets.compress = true

  # Don't fallback to assets pipeline if a precompiled asset is missed
  config.assets.compile = true

  # Generate digests for assets URLs
  config.assets.digest = true

So the comment "# Disable Rails's static asset server" should be changed to "enable"?

Did you test it / benchmark it? I haven't heared of using unicorn itself for serving static files.

I didn't put those comments in there, sorry they should be removed. They were from the normal production.rb.

I can confirm this works

Look at the headers.

$ curl -I http://d10jcizdv7jp27.cloudfront.net/assets/application-6b58f8d64acb2c27182c694b2fd87c8d.js
Cache-Control: public, max-age=31556926

Oh ok, and benchmark/comparison with "ordinary heroku"?
