Thanks for the assist. After some testing, it looks like it’s an advert plugin that uses PHP sessions which adds the Cache-Control:

Cache-Control: no-store, no-cache, must-revalidate
Pragma: no-cache
Expires: Thu, 19 Nov 1981 08:52:00 GMT

I’m investigating now if there’s anyway to adjust PHP settings so that it doesn’t break the CF caching

It seems to be random. We do have Anti Spam installed

I narrowed it down to one site. It occurs when I enable page cache.
