Plan Cache Busting Without Teaching Users to Hard Refresh
Define versioned assets, cache boundaries, rollback evidence, and acceptance checks for outsourced releases.
**Published: September 9, 2026**
When a release mixes old styles with new markup, asking visitors to clear their cache is not a durable fix. The deployment handoff needs an asset identity strategy.
Name the cache boundaries
List versioned scripts, styles, images, fonts, documents, HTML responses, and external caches. Record which layer controls each lifetime. Content editors should know when replacing a file at the same path can leave stale copies in circulation.
Make releases coherent
Prefer content-derived asset names or another proven versioning mechanism. Ensure generated pages reference the matching assets and preserve a rollback path. Do not append random query strings manually without an ownership rule.
Test ordinary visitors
Load the old release, deploy the candidate, then navigate normally in the same browser. Inspect response headers and requested filenames, test a clean session, and verify rollback behavior. Evidence should show that visitors converge on one coherent version without special instructions.
