Google Cloud CDN: Is WordPress Admin Panel accessed through CDN?

[Stanley Jobs]

Hey,

When Google Cloud CDN is enabled, is WordPress Admin Panel accessed through CDN?

If Yes, how to exclude wp-admin pages?

How does Google CDN handle dynamic pages?

Thank you

Hello Stanley,

According to this document, the web server application (nginx, apache, etc.) on the (wordpress) instance uses HTTP headers to indicate which responses should be cached, and which should not. You can check the requirements ( to configure your web server) of such headers at this link. As for dynamic pages, and pages that require real-time updates,  you may check this best practices document explaining expiration times configurations. I hope this helps.

Dear Fady,

My issue about Cloud CDN cache, I saw two urls below same cache object. The content of them loaded same.

A. https://domain.com/wp-admin/load-scripts.php?c=0&load%5B%5D=jquery-core,jquery-migrate,utils&ver=5.2.4

B. https://domain.com/wp-admin/load-scripts.php?c=0&load%5B%5D=hoverIntent,common,admin-bar,heartbeat,wp-format-library,shortcode,media-editor,media-audiovideo,mce-view,imgareaselect,image-ed&load%5B%5D=it,quicktags,wplink,jquery-ui-position,jquery-ui-menu,jquery-ui-autocomplete,thickbox,media-upload,svg-painter,wp-auth-check,jqu&load%5B%5D=ery-ui-datepicker,jquery-ui-draggable,jquery-ui-droppable&ver=5.2.4

How can I solve this issue?

Hello Khiem,

You need to set the expiration for time-sensitive content like this so its updated every certain amount of time. Wordpress documentation [1] further explains how to implement the Cache control HTTP header as well as plugins that will do it for you.
