Frequently Asked Questions

Common questions about Nginx Helper

No. You need to make some changes at the Nginx end. Please check our tutorial list. FAQ - Nginx Fastcgi Cache Purge

Yes, it does. It physically empties the cache directory. It is set by default to /var/run/nginx-cache/. If your cache directory is different, you can override this in your wp-config.php by adding define('RT_WP_NGINX_HELPER_CACHE_PATH','/var/run/nginx-cache/'); Replace the path with your own.

Yes. It handles all post-types the same way.

By default, Nginx Helper does not purge cache on WordPress core, plugin, or theme updates. If you want this behavior, you can enable it using a filter: add_filter( 'rt_wp_nginx_helper_enable_auto_purge_on_any_update', '__return_true' ); Once enabled, cache will be purged automatically whenever WordPress core, plugins, or themes are updated. If left disabled (default), Nginx Helper will instead show an admin notice after updates, reminding you to purge cache manually.

Manually purging any page from the cache, by following instructions in the previous answer. Version 1.3.4 onwards, Nginx Helper adds a comment at the end of the HTML source ('view source' in your favourite browser): . This shows the time when the page was last cached. This date/time will be reset whenever this page is purged and refreshed in the cache. Just check this comment before and after a manual purge. As long as you don't purge the page (or make changes that purge it from the cache), the timestamp will remain as is, even if you keep refreshing the page. This means the page was served from the cache and it's working! The rest shows you the database queries and time saved on loading this page. (This would have been the additional resource load, if you weren't using fast-cgi-cache.)

Nginx helper plugin handles usual scenarios, when a page in the cache will need purging. For example, when a post is edited or a comment is approved on a post. To purge a page immediately, follow these instructions: Let's say we have a page at the following domain: http://yoursite.com/about. Between the domain name and the rest of the URL, insert '/purge/'. So, in the above example, the purge URL will be http://yoursite.com/purge/about. Just open this in a browser and the page will be purged instantly. Needless to say, this won't work, if you have a page or taxonomy called 'purge'.

Yes. When setting the URL structure in Nginx configuration file a trailing slash should always be added.

Nginx Helper now includes optional WooCommerce integration. If enabled, cache for purchased products or products updated via REST API will be purged automatically. To use it: Go to Nginx Helper → Settings → WooCommerce Options. Tick “Purge product cache on updates”. This ensures customers always see up-to-date stock status and product information without stale cache. Note: This option will only be visible if WooCommerce is active. FAQ - Nginx Redis Cache

Yes, you can force override the redis hostname, port or prefix by defining constant in wp-config.php. For example: ` define('RT_WP_NGINX_HELPER_REDIS_HOSTNAME', '10.0.0.1'); define('RT_WP_NGINX_HELPER_REDIS_PORT', '6000'); define('RT_WP_NGINX_HELPER_REDIS_PREFIX', 'page-cache:'); `

Yes, you can force override the redis socket path, username, password by defining constant in wp-config.php. For example: `php define( 'RT_WP_NGINX_HELPER_REDIS_UNIX_SOCKET', '/var/run/redis/redis.sock' ); define( 'RT_WP_NGINX_HELPER_REDIS_USERNAME', 'admin' ); define( 'RT_WP_NGINX_HELPER_REDIS_PASSWORD', 'admin' ); ` FAQ - Nginx Map
