I’m using Rails api with an angularjs front-end which is served simply as static files under
directory (no sprockets or rails assets pipeline involved).
I’ve chosen passenger as the app server, deployed to heroku and everything seems to be working fine except for caching.
Since static assets are served directly by passenger/nginx, I’m thinking this has
nothing to do with rails, is this correct?
But I have no idea how to set cache headers or where to add configurations.
Response headers when requesting a static file (application-a24e9c3607.js):

Any help appreciated. Thanks.
