You’re welcome ??
Fresh Forms doesn’t include any specific support for it and it hasn’t been tested in a site using that.
The only documentation that I found for WP Egine’s Advanced Network doesn’t explain how it works internally or if it supports any kind of cache exclusion. The only mention to Cache is clearing it once manually from the panel.
But it’s supposed for that feature to just enable Cloudflare for your site, the only difference would be that you enable it from WPE’s control panel instead of going to a Cloudflare account dashboard.
The section linked in my previous reply explains that Cloudflare requires a cache-control header set for the page to exclude it from cache, and WPE doesn’t allow this. It also explains that, by default, Cloudflare doesn’t cache pages. It’s expected for this to be the case when you enable Cloudflare from WPE too, because WPE doesn’t allow other page caching solutions for their customers, therefore I bet they are just providing the Cloudflare integration to make use of the CDN and DDoS features.
In any case, it’s pretty easy to confirm if Cloudflare’s page cache is enabled for the site, just check the value for the cf-cache-status header in a page, if it says “DYNAMIC”, Cloudflare’s page cache is not enabled so you can forget about it.
