“We currently only support Session Affinity in “orange-cloud” (proxied) mode, though we intend to support “gray-clouded” (DNS-only) in the future.
Additionally while affinity is currently only available by cookie, in the future Cloudflare will also add support for Session Affinity by IP, as well as custom cookies and header”
There is some news when “gray-clouded” + IP affinity will be available?
This feature will be super useful for balance HLS edge stream servers using DNS, instead complicated balanced based on complex software!!
