This document describes a load balancing configuration using Varnish, Squid, and HAProxy across multiple servers. Traffic is cached and load balanced across servers hosting different domains. Varnish is configured with backends and directors to route requests to the appropriate caching servers for different domains, handle caching, and distribute traffic. Squid and puppet are also configured to share caches between servers and automate configuration respectively.
