Constants#

Docket Cache uses constants variable as main configuration methods.

Updated: 04-Oct-2026 | v26.04.07

Constants are like variables except that once they are defined they cannot be changed or undefined. To change the behaviour of Docket Cache, the following PHP constants can be defined in your wp-config.php file.

Docket Cache load the configuration by calling Constan::register_default() method that can be found in file includes/src/Constans.php. Some constant marks as @private and for internal use, changing it may result in unpredictable behaviour.

Default: 345600 (4 days)

define('DOCKET_CACHE_MAXTTL', 345600);

If there is no expire time was set to object or set to 0, Docket Cache will use this setting as an expiration time.
