In config/environments/production.rb I have set config.serve_static_assets = true config.static_cache_control = "public, max-age=1000" But the response header for application-fingerprint.css is something like the following where you can see max-age hasn't been changed to 1000. I'm assuming this is the result of some interaction with rack-cache but I don't know how to solve my problem. Age:2943 Cache-Control:public, max-age=3600 Connection:Keep-Alive Content-Encoding:gzip Content-Length:13851 Content-Type:text/css Date:Thu, 18 Oct 2012 01:24:20 GMT Last-Modified:Sat, 13 Oct 2012 02:52:50 GMT Server:WEBrick/1.3.1 (Ruby/1.9.3/2012-04-20) Vary:Accept-Encoding X-Content-Digest:94af71be4b455214a008971627ca52b848e40fc1 X-Rack-Cache:fresh

Since I normally handle all my headers via Apache or Nginx I don't remember if this is entirely the case anymore but again if I remember right everything again in /app/assets is considered compiled on the fly unless you compile it to /public.

I solved my problem by running RAILS_ENV=production bundle exec rake assets:precompile It appears that the setting for config.static_cache_control is being lazily cached. If I do the following, I get back max-age=1000 in the response header config.static_cache_control = "public, max-age=1000" precompile assets start webrick visit webpage However if I do the following I don't get back max-age=1000, instead I get max-age=2000 config.static_cache_control = "public, max-age=1000" precompile assets start webrick close webrick config.static_cache_control = "public, max-age=2000" start webrick visit webpage Can someone explain to me how this is possible and give a model for how config.static_cache_control is being saved?
