pdf.worker.js is not cached by CDN

I have configured CDN for my app, but pdf.worker.js and other static files are still hitting the rails server. How do I avoid this?

PDF js files are heavy and using CDN would improve the performance.

Hi, upon further investigations I can see assets on which stylesheet_link_tag eg is used are setting the cache-control headers correctly but assets which are linked directly do not set any cache-control headers eg.

This is an issue in production as viewer loads several different static files (around 35 files) which have to be downloaded from the origin server instead of being downloaded via the CDN.
