Message:

Cron API: Prevent caching of WP Cron requests.

Add Cache-Control and Expires HTTP headers to prevent caching of requests to WP Cron on systems supporting fastcgi_finish_request().

The fastcgi_finish_request() call prevents the setting of further HTTP headers by caching plugins subsequently loaded.

Props kingkero.
Fixes 47396.
