Browser & CDN Caching

Storing copies of resources to avoid repeated downloads on subsequent requests.

Effective caching uses Cache-Control headers (public, private, max-age, immutable) and ETag/Last-Modified validation. Long-cached static assets with cache-busting URLs deliver maximum performance. CDN edge caching extends benefits beyond individual users. Wix configures appropriate caching automatically across HTML, images, CSS, JavaScript and fonts.
