/**
* Defines no-cache constants for various WordPress plugins.
*
* This is compatible with Quick Cache, W3 Total Cache, and also with WP Super Cache.
* Quick Cache uses: ``QUICK_CACHE_ALLOWED``, and other plugins use: ``DONOTCACHEPAGE``.
* W3 Total Cache is also known to be compatible with ``DONOTCACHEOBJECT`` and ``DONOTCACHEDB``.
*
* Disallow caching if the ``$no_cache`` parameter is passed in as ``true``, by other routines.
* In addition, always disallow caching for logged in users, and GET requests with: `/?s2member` Systematics.
* For clarity on optimizeMember Systematics, see: {@link optimizeMember\Systematics\c_ws_plugin__optimizemember_systematics::is_s2_systematic_use_page()}.
*
* However, this routine will ALWAYS obey the `?qcAC` query string parameter.
* This Quick Cache parameter explicitly allows caching to occur.
*
* @package optimizeMember\No_Cache
* @since 3.5
*
* @also-called-by Other routines within optimizeMember.
*
* @param bool $no_cache Optional. Defaults to false. If true, force no-cache if at all possible.
* @return bool This function will always return `true`.
