Hello @Nathan Bird,
Thanks for reaching Microsoft Q&A.
Thank you for your patience here. I am just summarizing our private communication for community benefit.
As discussed, we currently do not have an ETA for when this feature will be supported by application gateway.
For anyone who is using AKS as backend can consider using Azure Application Gateway for Containers. This is expected to support the 308 response code once the Kubernetes Gateway API reaches a stable release in v1.5. The team will provide an update on Azure as soon as this support is available.
