FAQ

Partly. Cart, checkout, and account pages are automatically excluded from the page cache.

You can define the constant DONOTCACHEPAGE to prevent a page from being stored in the cache. To use it correctly, make sure it is defined early during WordPress execution — before output begins.

For example, in a plugin or theme:

add_action('template_redirect', function() {     if ( is_page('thank-you') || is_user_logged_in() ) {         define('DONOTCACHEPAGE', true);     } });

This ensures the current request is processed normally but not stored in the page cache.

Important:
If a page has already been cached, this logic will not run — because the cached version is served before WordPress reaches your code. To apply new exclusions like this, make sure to purge the page cache after defining the logic.
