Conditional Cache

do you want to use the buffer before creating cache?

No, I want to opt-out of using the cached page (without re-creating the cached page) in some situations. Either that, or have the ability to choose between ‘cached versions’ of a page. My backup solution is to exclude these pages from the caching entirely.

do you want to disable cache for some pages?

No, I only want to bypass using the cached version of a page for certain visitors. So, say I have a $_SESSION variable ‘no_cache’, I’d like to have the page render in full and not use the cache. When the variable is not set, I want to load the cached page.

it is not possible after created cache because PHP does not work.

Yes, but Must Use plugins execute before WP Fastest Cache, so I was hoping to be able to do something from there.

but if the cache is created one, you cannot execute PHP.

Doh, I just tested this; you’re right. I mistakenly thought there was still some PHP executed before requesting the cache.
