3 min readTo verify Apache caching is working, you can start by checking the response headers of a page request using a tool like cURL or browser developer tools. Look for headers like "Cache-Control", "Expires", "Last-Modified", and "ETag" to see if caching directives are being properly set.You can also monitor the HTTP requests and responses in your server logs to see if cached content is being served to clients. Look for log entries that indicate a cache hit or miss.
