Recently, I changed the website server and started using Tencent's EdgeOne service. Because I had to manually clear the cache in the EdgeOne Admin Dashboard after each Post update, I wondered if I could write a Plugin to achieve automatic refresh. Thus, this Tencent EdgeOne Cache Purge WordPress Plugin was born.

Then fill in theZone ID, check theEnable Auto Purgeoption, save the settings, and the configuration is complete.
In the manual purge interface, you can purge by Post ID or by URL.
After purging, you can view the records in the purge log.
Explanation about cache plugin integration
Currently, the plugin integrates automatic purge functionality for four caching plugins: WP Super Cache, W3 Total Cache, WP Rocket, and LiteSpeed Cache. When you purge the cache in your caching plugin, the EdgeOne plugin will automatically purge the CDN cache.
However, Naiba's own website usesNginx Fast_cgi cache. I have only tested with W3 Total Cache with a friend. If your caching plugin's purge does not automatically clear the CDN cache, please manually purge once in the EdgeOne cache plugin.
