A few weeks ago I was working on #webperf for my Hugo blog... I didn't fully understand #caches, cache-control headers, and I think I made a bad mistake of using the immutable flag on HTML content and a cache time of 1yr 🫣 thinking it will be fine as I purge the storage on every deployment.
But I noticed stale content unless force refreshing pages. 😫 I think I fixed it now with #Hugo fingerprinting and setting different cache times for assets and HTML content.
