Page Cache

Found answer later in FAQs

Gotta love those FAQ’s ??

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)
