Cache-Control Header Builder

Build the exact header you mean, not the one you guessed

Cache-Control Header Builder lets you toggle real HTTP directives — public/private, max-age, s-maxage, no-cache, no-store, must-revalidate, proxy-revalidate, immutable, and stale-while-revalidate — and builds the correctly-formatted header string live. Plain-English explanations and one-click presets take the guesswork out of a header that's easy to get subtly wrong.

• →Builds the correctly-formatted header string live as you toggle options
• →Explains what each combination actually means for browsers versus CDNs and shared proxies
