Nginx has a built-in FastCGI cache, which acts as a reverse proxy cache at the webserver layer. The Cache Sniper for Nginx WordPress plugin lets you purge this cache from within WordPress. Here are some key features:
- Purge the entire cache from the menu bar
- Manually purge individual pages
- Manually purge homepage cache
- Configure pages to purge automatically when updated
- Configure pages to purge automatically when comments are created/updated/deleted.
- Configure Settings via WP CLI
