Hi, @robert, there is no follow-up blog post. I believe it was mentioned only as a hypothetical post and I don’t know if the author ever actually intended to create it.
With assets hosted on our CDN, we’ll use the following header:
cache-control: public, max-age=0, must-revalidate
For assets that have been processed by our asset optimization, the header looks similar to this instead:
cache-control: public, max-age=31556926
This allows for the long-term caching of the asset.
Please let us know if there are any other questions about this.
