But more than basic cache management, you can also use helpful plugins to trigger event-driven cache operations. For example, if you display the latest posts on your homepage, it would be helpful in the cached home page was purged whenever a new post is added.

NGINX Helper Plugin Features

There are a few important features available in the NGINX helper plugin you should know about. We will be primarily focusing on the purging options available. These help NGINX determine which pages you would like to purge, or which events will trigger the purging of a certain page from the cache.

Purging options

To access the purging options, you must only check the box labelled Enable Purge under Purging Options in the NGINX Helper settings.

Purge conditions Once the purge options have been enabled, you will see the Purging conditions box appear. It is important to note which events will trigger a purge. For example, the first option allows you to purge your homepage when a post is added or modified. This would be especially important if your homepage displays a list of recent posts.

Purge Entire Cache

Purge Entire Cache Button The Purge Entire Cache cache resides at the topmost right hand section of the page. This procedure is to be avoided for most of your every day maintenance needs.

Purging the entire cache will cause your WordPress website to suffer performance lags as Ngnix rebuilds the cache. This option should only be used if you really intend to purge all cached data. You must be prepared to allow adequate time for the cache to rebuild its resources.

Debug (Logging) Options

Nginx Helper log The Ngnix Helper provides detailed logs of its activities. You can find the logging features under the Debug Options section.

Turn on the Enable Logging button Check the Enable Logging box to active the logging feature.

Logging Options The Logs path table shows you the path to the log. Click the Log link to see the log displayed in your browser. Log level determines the level of detail the logs will provide, and Max log file size allows to cut off the log when the file reaches a certain size.
