103 Early Hints and AWS ALB

[ba221400]

We would like to implement 103 early hints, and it got it working locally in a docker container (with and without ssl). However, our test and production environments are in AWS behind an ALB. From what we can tell, ALB doesn't currently support 103 early hints. We are still researching options and wanted to check with this community to see if anyone has found a solution for this problem?

I think I saw @withinboredom mention somewhere on this forum once that he got it working with an ELB. Caddy TLS etc should work if you just forward on the network layer and don't do application load-balancing. You obviously loose the ALB features though.
