Browser Cache Control Without mod_headers: The PHP filemtime Strategy
PHP filemtime으로 캐시 무효화하기—header 없이 간단하게
Why it matters
Stale cached content is a persistent problem for web developers—new articles or updates remain invisible until users manually clear their browser cache. This article reveals how PHP's filemtime() function offers an elegant solution through URL versioning: browsers continue leveraging local cache when files haven't changed, but automatically refetch when timestamps shift. It's a lightweight, header-free approach perfect for developers on shared hosting.
