Developer releases tool explaining costly HTTP caching mistakes
Original: I built cachewhy around a small but costly HTTP cache mistake. Imagine a request for /missing.js... # opensource # showd
A developer has built cachewhy, an open-source tool centred on a common but expensive HTTP caching error: a request for a missing file such as /missing.js can be cached, so the file stays missing even after a fixed deployment. The release is being shared with developer communities, with discussion focused on why stale cache entries break sites after updates.
Why now: It is a newly released open-source tool addressing a widely experienced deployment bug.
