		 * are used in the HTML. This allows removing only those cache entries
		 * whose content has really changed and only that entries have to be
		 * rebuild the next time.
		 *
		 * The standard behavior stores only tags for each used domain, e.g. if
		 * a text is used, only the tag "text" is added. If you change a text
		 * in the administration interface, all cache entries with the tag
		 * "text" will be removed from the cache. This effectively wipes out

		 * request.

		 * Important: As a list or detail view can use several hundred items,
		 * this configuration option will also add this number of tags to the
		 * cache entry. When using a cache adapter that can't insert all tags
		 * at once, this slows down the initial cache insert (and therefore the
		 * page speed) drastically! It's only recommended to enable this option
