HD3D The extension shouldn't cause any conflicts with Cloudflare. It operates similarly to enabling edge caching on Cloudflare. Pages are stored as static versions so they don't have to be regenerated.
The extension does not cache the admin panel. Its primary focus is to improve the performance for non-logged-in users (e.g., traffic from Google). Each non-logged-in user sees the same version of the page, allowing us to generate a single static version of each page. This approach significantly reduces the server load, making your website faster and more efficient.
If you're interested in using edge caching on Cloudflare specifically, a separate, dedicated extension would be needed for that purpose. That specialized extension would instruct Cloudflare on how to cache the pages and when to purge them. It's indeed possible to develop a framework that would be compatible with Flarum and various extensions. This framework could serve as a universal full-page caching solution specifically aimed at extension developers, allowing for easy integration with different caching systems including Cloudflare and LSCache.
