<a href="https://cloudflare.com" rel="nofollow ugc">CloudFlare</a> is a popular CDN service. They caches static files like <code>.jpg</code>, <code>.css</code> or <code>.html</code>, but they doesn’t cache dynamic pages generated by WordPress without <a href="https://www.cloudflare.com/features-page-rules/must-use-page-rules/" rel="nofollow ugc">Page Rule</a>.
Once Page Rules are set, for exmple, <code>https://examle.com/article/*</code>, every single page will be cached(of course, your permalink structure should be like <code>https://example.com/article/2019/01/01/POST_ID</code>).
This plugin hamecache provides cache control feature. If you update your article, hamecache automatically flush related caches on cloudflare edge location.
