Episode 71 of The Web Development Podcast with Fexingo: Lucas and Luna dig into a subtle but common service worker bug — caching HTML responses that go stale and never update. They walk through a real-world case where a user's dashboard showed outdated data for weeks, trace the problem to incorrect Cache-Control headers and a missing update handler, and show how to fix it with cache-first then network update patterns. If you've ever deployed a service worker and seen users stuck on old pages, this episode explains exactly why and how to prevent it.
