a second similar request not reach rails. views not renderd. page taken cache.

but in log looks different.

i use: rails 4.0.0

jruby

puma server

start server - rails_env=production rails s puma

in controller use

and root url.

my gemfile

    gem 'rails', '4.0.0'     gem 'activerecord-jdbcpostgresql-adapter', '~>1.3.0.beta2'     gem 'dalli'     gem 'jquery-ui-rails'     gem 'jquery-rails'      group :assets       gem 'coffee-rails', '~> 4.0.0'       gem 'uglifier', '>= 1.3.0'       gem 'therubyrhino'       gem 'execjs'     end      group :development         gem 'annotate'         gem 'puma'     end      gem 'dimensions-rails'     gem 'sass-rails', '~> 4.0.0'      group :production       gem 'rack-cache'       gem 'actionpack-page_caching'     end 

please me understand wrong.

when using page caching should instruct webserver serve cached pages written in public directory. idea if normal path request /foo/bar.html cached copy should stored in rails.root/public/foo/bar.html. way request never hits rails application.

when changing storage path public/deploy have done, should take care point webserver directory serve files there. don't think puma handles that, should handle in frontend server (like apache or nginx).

having said that, page caching removed rails 4 reason, prehaps should russian doll caching it's more flexible , easy use.
