Are there any example to apply ACCEPT_CH frame on loadbalancer?

[jen6]

I have tried using the CRITICAL-CH header(#123) to request a client retry when client hints were missing due to out-of-date preferences. However, I understand that this approach may not be suitable in certain cases, as it requires the load to restart in order to return the now-cached client hints.

In light of this, I am interested in finding an alternative solution such as the ACCEPT_CH frame, which may allow me to avoid the retry in most cases by delivering the client hints as part of connection setup.

Therefore, I am specifically looking for examples or documentation on how to implement the ACCEPT_CH frame on a load balancer, rather than the CRITICAL-CH header. Could someone provide an example or point me to some documentation on how to implement the ACCEPT_CH frame on a load balancer? I would greatly appreciate any guidance on this topic.

Thank you!
