Package org.mockserver.netty.proxy

Class ConntrackOriginalDestinationResolver

java.lang.Object

org.mockserver.netty.proxy.ConntrackOriginalDestinationResolver

All Implemented Interfaces:

TransparentProxyHandler.OriginalDestinationResolver

public class ConntrackOriginalDestinationResolver
extends Object
implements TransparentProxyHandler.OriginalDestinationResolver

Resolves the original destination of a transparently intercepted TCP connection by reading the Linux conntrack table (/proc/net/nf_conntrack).

This is the default strategy for transparent proxy mode on Linux. It delegates to SoOriginalDstHelper.getOriginalDestination(Channel), which parses the kernel conntrack table to find the pre-iptables -j REDIRECT destination.

On non-Linux platforms, this resolver throws UnsupportedOperationException, which the CompositeOriginalDestinationResolver catches and continues to the next strategy.
