FlyingPress automatically sets long browser cache TTL headers for static files, helping them get cached efficiently. This helps resolve the “Serve static assets with an efficient cache policy” warning in Google PageSpeed Insights.
Possible Reasons:
Unsupported Web Server
FlyingPress can set these headers only if your server is Apache, LiteSpeed, or OpenLiteSpeed.
If you’re using Nginx, you’ll need to either:Contact your hosting provider, or
Manually update your Nginx config.
Third-Party Scripts
Browser caching policies for third-party resources (e.g., fonts, ads, analytics) cannot be controlled by FlyingPress or your server.
