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