How to verify apache caching is working?

There are a few ways to verify that Apache caching is working:

1. Check the HTTP headers: When you load a web page in your browser, you can check the HTTP headers to see if caching is enabled. Look for headers like "Cache-Control", "ETag", or "Last-Modified" that indicate the caching settings for the page.
2. Use browser developer tools: Most modern browsers have developer tools that allow you to see network requests and responses. You can use these tools to check whether the browser is fetching resources from the cache or from the server.
3. Monitor cache hit rate: You can use server monitoring tools to track the cache hit rate, which shows how often requests are served from the cache instead of being fetched from the server. A high cache hit rate indicates that caching is working effectively.
4. Test caching behavior: You can test the caching behavior by making changes to your website and checking if those changes are reflected in real-time. If the changes are not immediately visible, it means that caching is working and serving cached content.

By using these methods, you can verify that Apache caching is working properly and helping to improve the performance of your website.
