It will purge on a save, regular update, quick edit update, slug change, delete and undelete. The user is informed with one or more messages. There are a few caveats: When a user is using the Gutenberg editor, purge messages will not be displayed. When the user uses “Quick edit” and “Updates” the post, no messages will be displayed, because there’s no page refresh. Those messages will be shown on the next request. It is possible to purge with WordPress cronjobs. Adjust the ‘Cronjob settings’ to perform a daily purge of caches. You can also purge items manually.

Remember that this file must contain information about all servers, including this one. Default path is: /uploads/cachelong-cache-control/hosts.json. Here is an example of a hosts.json file: {“servers”: [ {“name”: “server1”, “ip”: “127.0.0.1”, “pagespeed”: true, “fastcgi”: false}, {“name”: “server2”, “ip”: “127.0.0.2”, “pagespeed”: false, “fastcgi”: true}, ] } Each line contains information about one server. Parameters: name string Name of host, something to identify this server. ip string IP address of server or full url. Format: scheme://host:port/path pagespeed bool Server uses Nginx Pagespeed (true) or not (false) fastcgi bool Server user Nginx FastCGI (true) or not (false) When there is no hosts.json or the path is invalid, this plugin assumes the following: {“servers”: [ {“name”: “localhost”, “ip”: “127.0.0.1”, “pagespeed”: true, “fastcgi”: true} ] } How does it work “Cache control by Cacholong” empties partial or full cache for Nginx Pagespeed and FastCGI cache. WordPress HTTP API is used to make (post) request to specific urls to trigger purges. Based on the http header responses this plugin determines if a purge is successful or not. The user is informed with messages, which are loaded after a purge and page refresh. There are several settings to tweak purging, see Settings > Cache control. WP-CLI There are several commands available for the commandline with wp-cli. Commands generate text output which can be suppressed with –quiet. When an error occurs, text will always be displayed. WP-CLI (exit codes) Exit codes are 0 (no errors) or 1 (generic error). wp cacholong_cc purge Purge either Nginx FastCGI, Nginx Pagespeed or all caches. wp cacholong_cc purge_all Purge all caches. wp cacholong_cc factory_reset [–site_id=site_id] Factory reset options for given site_id or current blog if no site_id is given.
