Hi,
We want to use Undertow in our company (Oath/Yahoo/Verizon) in an AWS environment. Since we plan to use AWS Network Load Balancers (NLB) using Fargate, we need the proxy protocol in order to get the source IP address of an incoming HTTP(S) packet. However, Undertow only supports Proxy Protocol Version 1. I have implemented version 2 (for IPv4 and IPv6), including unit tests and it works fine. I wonder if I can contribute the code to the open source release of Undertow.
Let me know if you are interested, then I can provide the code.
Best regards
Ulrich
