Class HaProxyProtocolDetectionHandler

java.lang.Object
io.netty.channel.ChannelHandlerAdapter
io.netty.channel.ChannelInboundHandlerAdapter
io.kroxylicious.proxy.internal.HaProxyProtocolDetectionHandler
All Implemented Interfaces:
io.netty.channel.ChannelHandler, io.netty.channel.ChannelInboundHandler
public class HaProxyProtocolDetectionHandler extends io.netty.channel.ChannelInboundHandlerAdapter
Uses HAProxyMessageDecoder.detectProtocol(ByteBuf) on the first bytes of a connection to decide whether to install the PROXY protocol decoder.

In ProxyProtocolMode.REQUIRED mode, non-PROXY bytes cause the connection to be closed with a warning. In ProxyProtocolMode.ALLOWED mode, non-PROXY bytes are simply passed through to the Kafka decoder.

This handler is not used when the proxy is in ProxyProtocolMode.DISABLED mode.

This handler removes itself from the pipeline after the first read.
