 * Hi,
 * When you say the following does it mean i need to have my caching plugin disabled
   in order to allow the critical css rules to be generated?
 * “To get critical CSS going, make sure there are requests coming in that are not
   served by a page cache”

 * Yup, that’s my fault for jumping ahead excitedly! 🙂
 * Although, saying that, after using the plugin i’m a little unsure as to whether
   the page cache needs to be disabled entirely until the critical css is generated/
   updated (which is what i did based on my interpretation of the faqs).
 * The thing is i keep my cache built all the time (as my pages rarely change), 
   so cache is usually only cleared manually or when my theme forces me to do it.
 * The first hit needs to be uncached to start the process, but does it require 
   a second uncached hit also?
 * What i would do under normal circumstances is after page cache has been cleared,
   to use xenu link sleuth to quickly spider my site and regenerate the page cache.

 * there’s no clear-cut answer, but what you could do:
 * 1. clear page cache to allow jobs to be created
    2. jobs result in rules 3. if
   you have your most important rules (e.g. is_front_page, is_single, is_page, …)
   you can again clear page cache to ensure the CSS is injected in your HTML (instead
   of serving pages from cache that don’t have the rules applied yet)
