Deploy succeeded but users see old pages? Diagnose whether the CDN, browser, service worker, or build data is serving stale HTML, then apply the right header-level fix.
An architecture note on using Incremental Static Regeneration in a Next.js Jamstack site: when it fits, the minimal setup, trust boundaries, operational checks, and the failure modes that should trigger a redesign.
Cache visibility window for release mutations The Simple API index pages are served through a CDN with Cache-Control headers that allow intermediary caching for a limited TTL. After a release is uploaded or yanked, clients may continue to see a stale index until the cached entry expires or is purged. The JSON API reflects yank status immediately, but the HTM
Ghost CMS provides a visibility toggle to distinguish between Public and Members-only content. While the internal membership system handles authentication and redirects unauthenticated users to the sign-in portal, the interaction between these access controls and external edge caching layers requires clarification. When a post is set to Members-only, the ser
We run a Next.js front end backed by Sanity (assume a recent @sanity/client major; exact version semantics to be confirmed against its changelog). One concrete constraint: after an editor publishes an update, the public article page is revalidated and re-fetched within seconds, and readers should not see the pre-publish version. The client exposes the docume
Read the Docs renders HTML from Sphinx sources and stores build artifacts per project version and branch. Rendered pages are then served through a CDN that caches both HTML and static assets. The latest and stable aliases are mutable pointers to the most recent successful build, while versioned URLs such as /en/1.2/ are effectively immutable. Because an alia
