The cPanel in your WordPress-optimized server uses Nginx as a powerful caching proxy in front of Apache. This means your visitors will enjoy quick page loads with less effort on your part.

As the site administrator or developer, you have access to a new suite of tools in your WordPress-optimized cPanel.

What does this cache do?

For beginners, we'll explain a little bit about what caching is and why it is so important for a WordPress site. If you're an experienced user, you can skip ahead to the Cache Manager features for cPanel.

WordPress uses PHP (scripting language) and MySQL (database) to generate a page equivalent to a basic static HTML page. The process of generating the page uses computing power in the server. Once the page has been created, there's no need to generate it again unless something has changed. If nothing has changed, we can use Nginx to "cache" the complete page and store it for use later. This means the page will load faster from the cached resource.

In the section below, you will learn how you can leverage the caching resources intelligently. Nginx will be able to detect if something has changed on a page, and it will reload the changes into the cached file automatically. However, if you are making a lot of changes to the site and want to see instant results, you can read on to learn how you can suspend caching temporarily.

Cache Manager Features

Save Changes Your WordPress-optimized server comes with a power Cache Manager tool you can use to intelligently manage cached resources. In the sections below, we will introduce you to some important features of the Cache Manager. Make sure to click the Save Changes button after making any changes.

Selecting a Domain

Select a domain If you are managing multiple domains in your cPanel, you can simply select the one for which you want to affect cache management.

Purge URL

Purge URL You have the option to purge the cache for a single page using the Purge URL option. Simply paste the URL of the page to purge and click the Purge button.

Enable Caching

If you are making a high number of radical changes to the site, and you want to see changes immediately, you will want to disable caching. This will suspend caching while you are working on the site, so you can see changes without having to repeatedly flush the cache.

Default Refresh Time

Default refresh time The default refresh time tells the caching service how long it should wait before checking for updates to your website.

Bypass URL

Bypass URL The bypass URL setting tells the caching service which URLs should never be cached. These URLs will always be loaded directly from the server and never from the page cache. To add a new URL, click the + button. Conversely, to remove a URL use the X button.

Purge Full Cache

Purge Full Cache There may be occasions in which you want to apply changes to all domains. The Purge Full Cache button will effectively purge the cache for all domains owned by your cPanel user.

There is no average response time, The time will differ vastly depending on your site. For example if your page is a static informational page it will respond very quickly however if you have a site that needs to make several database calls or pull information from external sources for live data it may have to wait for those calls to complete before it starts to respond.

Hi, I recently enabled the cache maneger, I would like to know what is the optimal value under "Default Refresh Time" and why, and if possible what are the steps to be done when adding products on the site, or when editing texts.

 

Thank you

The optimal "Default Refresh Time" depends on your specific site. For example, if you are updating and adding products regularly, you will want to refresh the cache more often. You should not have to do anything special when adding products and text, but if you are not seeing updates you may want to purge the page URL as described above.

Thank you,
John-Paul

So, where do I find the Cache Manager? I do not see it as an option in my cPanel. Also, I'm using WP Super Cache as a plugin on my site. If I were to use the Cache Manager, would I be able to remove that plugin to help streamline my site? I'm trying to speed up my site and having only average results so far. Thanks.

Ideally, you can use this feature for your major caching needs, and you will likely not need any additional plugins. However, there are plugins that help you manage the Ngnix caching you already have from within WordPress.

I added the NGinx helper plugin as recommended in the upgrade email when we switched the wordpress hosting service, but it does not appear to do anything. I read the help page you have on the plugin and it does not say you have to set it up in any way special. Are there any spcific settings that need to be made in the nginx helper plugin to make it work?
