在RAILS 3.1中的js资产上设置Cache-Control标头

Question

我检查生产服务器上的标题为

    curl --head -H "Accept-Encoding: gzip" http://foo.heroku.com/assets/mobile.js

然后我回到以下标题,建议RAILS不设置cachecontrol标头.

HTTP/1.1 200 OK
Server: nginx/0.7.67

我想让heroku的清漆缓存缓存资产,只在git push上刷新.关于如何获得这个的任何想法？

您必须在您的environment/production.rb中添加它:

config.serve_static_assets = true
config.static_cache_control = "public, max-age=172800"
