I am experiencing issues with integrating Cloudflare and CMS Grav. After enabling Cloudflare and configuring cache rules (Cache Rules), I have noticed two main problems in the admin panel (/admin):
After clicking “Log out,” I get the message “You have been logged out”, but the admin panel remains visible. I am not sure if this is a cache issue or a problem with Grav sessions.
The admin panel and its subpages, as well as actions like saving pages, are significantly slower compared to before configuring Cloudflare. I suspect that Cloudflare is acting as an intermediary and causing delays.
Current Cloudflare Cache Rules Configuration:
Cache Everything (Template)
(http.host contains "example.com")
→ Caches the entire site, including static assets.
Bypass Cache for Admin
(starts_with(http.request.uri.path, "/admin"))
→ Should disable caching for /admin and its subpages.
Bypass Cache on Cookie (Template)
(starts_with(http.cookie, "grav-site"))
→ Should bypass cache if the user has a Grav session.
Additional Information (cf-cache-status headers). For public site subpages (example.com/*), the response header is:
cf-cache-status: HIT
For the admin panel (example.com/admin/*), the response header is:
cf-cache-status: DYNAMIC
(Cloudflare is not caching, but it is still acting as an intermediary.)
