We don't have particular test patterns, so I guess that you'll just have to proceed like all other implementors, by placing a reverse proxy supporting the proxy protocol in front of your server to validate that it works as expected. Haproxy implements both version 1 and version 2, I tend to think that once you've validated that you should be OK with other implementations. V1 is very simple. V2 supports extended fields to pass TLS information for example. So if you use haproxy to offload TLS and use V2 to talk to your server and it still works as expected, you're likely to have got it right. Regards, Willy
