- Smart caching – content‑based hashing for instant cache validation
- HTTP/3 preload – automatic
Linkheaders for learned resources (requires APCu) - CDN ready – configurable cache URL for any delivery network

Advanced
Send preload headers early
Call sendCachedPreloads() before any output to let the browser discover critical resources sooner. You can pass a template name (used as APCu key).
Disable APCu learning
Clear cache
Manually delete all files in cache_dir or use the cache manager’s method if you expose it:
Requirements
- PHP 8.5+
- Smarty 5.7+
- APCu (optional, for preload learning)
wikimedia/minify(installed automatically)
Troubleshooting
Empty src/href attributes on Windows
Make sure all paths use forward slashes. The latest version normalises paths automatically – update to the current release.
Cache not written
Check that cache_dir exists and is writable by the web server.
Preload headers not sent
Verify APCu is installed and enable_apcu is true. Headers are sent only once per request.
Double slashes in URLs
Do not add a trailing slash to cache_url – the library adds it internally.
APCu required warning during install
The package checks for APCu; if you don’t need preload, you can ignore the warning or set enable_apcu to false in config.
