Application Cache: Douchebag

on YouTube ↗31m

" summary

Claim: Application Cache provides offline power but reliably breaks assumptions. Specifics: the manifest is all-or-nothing manifest so caches only install when every listed file succeeds; updates occur only when the manifest changes thanks to byte-for-byte validation, often requiring two refreshes; use network and fallback sections to avoid silent failures for uncached assets; sandbox the cache to one hidden iframe page and store user-picked pages in localStorage indexing for per‑page offline content — demos (spritecow, MDOT lanyard) work but with fragile update and error behavior.
