Is there any way to ask cloudflare talking to origin with ESNI?

Security
#1

if possible,
where is the document that explains how to config origin nginx and cloudflare settings?

#2

This is not currently possible for a couple of reasons:

  1. I don’t believe nginx supports ESNI - the spec itself for ESNI is still in draft ( https://datatracker.ietf.org/doc/draft-ietf-tls-esni/ ) so I don’t think you would be able to get an origin with nginx & ESNI support
  2. We don’t yet support making a request using ESNI to the origin - I’m not aware of any plans to do so yet but @akrivit might know more
