Oh didn’t realize it was a wiki.
I’m a novice with sysadmin/cloud stuff, so hopefully someone can double check me before I make any edits.
These are the missing headers I see in non-CDN /assets but missing in CDN /assets:
- content-encoding
- expires (though there’s x-amz-expiration)
- server
- X-Firefox-Spdy
When I compare to meta.discourse.org’s cloudfront CDN /assets headers, they’re missing expires (and x-amz-expiration), but have all the other headers compared to non-CDN /assets.
content-encoding seems like the most likely cause of the problem, which lines up with Digitalocean block storage VS amazon S3 - #5 by md-misko.
I also found two open DO community questions, not sure if they’re 100% the same root cause. Hopefully someone can double check me
