How can I cache font files on WordPress [closed]

In nearly all of the case WP doesn’t participate in serving static files. Its rewrite rules are typically configured to ignore them and let web server handle.

Otherwise overhead of firing up PHP engine and WP core for each static request would be incredibly taxing.

As such there is no mechanism in WP to deal with caching issues for static files (outside of some concatenation of admin assets for core use only).
