[Feature request] Cache for logged in users

@devprollc please don’t open duplicate support threads. You’ve been involved in the following threads related to this same topic:

• https://wordpress.org/support/topic/feature-to-be-able-to-serve-a-cached-version-to-logged-in-users/
• https://wordpress.org/support/topic/need-to-do-cache-for-logged-in-users/

If you have a question regarding a same topic it’s much easier if you add to the topic that is already open (if it’s not been closed yet). Caching for logged in users has been supported since version 1.4.0. This is handled in the cookies Cache Exclusions option. To deliver cached pages for all logged in users simply set a new cookies exclusion that doesn’t have wordpress_logged_in_ (e.g. /^(wp-postpass|comment_author)_/).
