Sprocket's hack to

server.md

Just take this source from sprockets' server.rb:

          if attributes_for(env["PATH_INFO"]).path_fingerprint
            headers["Cache-Control"] << ", max-age=31536000"

          # Otherwise set `must-revalidate` since the asset could be modified.
          else
            headers["Cache-Control"] << ", must-revalidate"
          end

and comment out this stuff:

          # if attributes_for(env["PATH_INFO"]).path_fingerprint
            headers["Cache-Control"] << ", max-age=31536000"

          # Otherwise set `must-revalidate` since the asset could be modified.
          # else
            # headers["Cache-Control"] << ", must-revalidate"
          # end

and once cached, Chrome starts acting like all the other browsers.
