Proxy Protocol Support

Evidence

Server-side mod: Kiln runs mods' code on Horizon's single-player server, not on dedicated servers.

What it needs from Kiln

• Mixin
• io.netty.bootstrap.ServerBootstrap
• io.netty.buffer.ByteBuf
• io.netty.channel.Channel
• io.netty.channel.ChannelHandlerContext
• io.netty.channel.ChannelInboundHandlerAdapter
• io.netty.channel.ChannelInitializer
• io.netty.channel.ChannelPipeline
• io.netty.handler.codec.ProtocolDetectionResult
• io.netty.handler.codec.ProtocolDetectionState
• io.netty.handler.codec.haproxy.HAProxyCommand
• io.netty.handler.codec.haproxy.HAProxyMessage
• io.netty.handler.codec.haproxy.HAProxyMessageDecoder
• net.fabricmc.api.DedicatedServerModInitializer
• net.minecraft.network.Connection
• org.apache.logging.log4j.LogManager
• org.apache.logging.log4j.Logger

On the roadmap: Minecraft's libraries and client API (0.2), Code next to data (0.3), Mixin (0.5)
