Performance
CDN mode or local cache
CDN mode
Default behaviour: load.js is loaded live from cdntag.tarteaucitron.io on every visit.
Local cache mode
The module downloads load.js once, serves it alongside the site's own assets, then refreshes it automatically after a cache duration (in days) that you set.
The settings screen always shows the cache status (CDN mode, Cache active, Cache expired, Not downloaded, Invalid cache, UUID changed…) plus a button to force an immediate re-download. If the download fails, or the tarteaucitron.io licence does not cover the domain, the module falls back to the CDN automatically rather than serving an invalid cache.
