138		- * Defines no-cache constants for various WordPress plugins.
	138	+ * Defines no-cache constants/signals for WordPress caching plugins.
139	139	*
140		- * This is compatible with Quick Cache, W3 Total Cache, and also with WP Super Cache.
141		- * Quick Cache uses: ``QUICK_CACHE_ALLOWED``, and other plugins use: ``DONOTCACHEPAGE``.
142		- * W3 Total Cache is also known to be compatible with ``DONOTCACHEOBJECT`` and ``DONOTCACHEDB``.
	140	+ * `DONOTCACHEPAGE` is the de facto cross-plugin page-cache bypass signal.
	141	+ * Legacy s2Member cache flags are retained, with explicit runtime APIs/filters
	142	+ * for popular caches that expose their own no-cache mechanisms.
143	143	*
144	144	* Disallow caching if the ``$no_cache`` parameter is passed in as ``true``, by other routines.
145	145	* In addition, always disallow caching for logged in users, and GET requests with: `/?s2member` Systematics.
146	146	* For clarity on s2Member Systematics, see: {@link s2Member\Systematics\c_ws_plugin__s2member_systematics::is_s2_systematic_use_page()}.
