To check if caching is working on your website, use performance analysis tools like Google PageSpeed Insights or GTmetrix. These tools scan your site and provide detailed reports on speed, including whether caching is enabled and effective.
If caching is working correctly, you’ll typically see fewer server requests and faster load times for static content such as images, stylesheets, and scripts.
You can also use your browser's Developer Tools (press F12 in most browsers) and view the Network tab. Look for files marked as being loaded from the cache rather than directly from the server—this indicates that browser-side caching is active.
