Compress and cache static assets aggressively

Compress and cache static assets aggressively | BeforeMerge Rules | BeforeMerge

Why this matters

Content-hashed filenames let you cache assets effectively forever; a new hash busts the cache on change. Text compression (Brotli/gzip) cuts JS/CSS transfer by 70-90%.

# bad: no caching, re-downloaded every visit
Cache-Control: no-cache
 
# good: immutable, year-long cache for hashed assets
Cache-Control: public, max-age=31536000, immutable

Ensure your server/CDN serves Brotli (or gzip) for HTML, JS, and CSS and sets immutable on hashed bundles.
