I am running a Rails 3.0.9 app on Heroku’s Cedar stack and have S3 serving static assets. In my production.rb file, there was a config set to:
config.serve_static_assets = false
If I change this to true, will it serve cached content quicker, or should I leave it as is?
From rails guide:
config.serve_static_assets configures Rails itself to serve static assets. Defaults to true, but in the production environment is turned off as the server software (e.g. Nginx or Apache) used to run the application should serve static assets instead. Unlike the default setting set this to true when running (absolutely not recommended!) or testing your app in production mode using WEBrick. Otherwise you won´t be able use page caching and requests for files that exist regularly under the public directory will anyway hit your Rails app.
Hope this helps.
