For clarity, are you referring to "sticky HTTP sessions" as identified by session cookie, like [1]?
In this implementation style, what happens to active sessions when the assigned backend host is decommissioned or restarted? --Ben Schwartz [1] https://developers.cloudflare.com/load-balancing/understand-basics/session-affinity/#cookie ________________________________ From: Gould, James <[email protected]> Sent: Thursday, February 19, 2026 2:39 PM To: [email protected] <[email protected]>; [email protected] <[email protected]>; Ben Schwartz <[email protected]>; [email protected] <[email protected]>; [email protected] <[email protected]>; [email protected] <[email protected]> Cc: [email protected] <[email protected]>; [email protected] <[email protected]>; [email protected] <[email protected]> Subject: Re: [regext] Re: draft-ietf-regext-epp-https-02 early Httpdir review Andy, Cloud HTTP gateways do support sticky HTTP sessions, which is what is used by draft-ietf-regext-epp-https.

Use of the CONNECT HTTP method does not meet this goal. I am befuddled by the "cloud-friendly" marketing as well. There are currently several RSPs who operate EPP using cloud providers, and many cloud providers have network load balancers that do TLS termination. From what I can tell, this draft doesn't work well with cloud-based web-application firewalls as each EPP operation uses the same path (or did I miss something), requiring custom parsing of the EPP XML bodies to do any app-layer routing. Can you point to the specific technical challenge this is referencing? Mario's message seemed to indicate that the desired connection model was about using reverse proxies which can be done on-prem or in a cloud. From that, I believe the issue he is solving is the lack of graceful session closure by the server in EPP. I am only guessing, but that seems like it could be solved with a simple EPP extension. -andy, as an observer
