Usage

E.g you can set CORS headers:

In config/environements/production.rb:

config.middleware.insert_before(ActionDispatch::Static, Rack::CustomHeader, {'Access-Control-Allow-Origin' => '*', 'Access-Control-Allow-Methods' => 'GET, POST'})

Make sure to include this middleware before ActionDispatch::Static and serve your static assets using rails.
