Previously, a user avatar redirect had a lifetime of 24h. That means that a change to the S3 CDN URL would take up to 24h to propagate to clients and intermediate CDNs. This commit reduces the max age to 1 hour, but also introduces a `stale-while-revalidate` directive. This allows clients and CDNs to use a 'stale' value if it was received between 1h and 24h ago, as long as they make a background request to update the cache. This should reduce the impact of S3 URL changes. 1 hour after the change, the CDN will start serving updated values. Plus, if users have cached bad responses, their browser will automatically fetch the correct version and use it on the next page load. |
