At the URL below, you can see a trimmed version of my haproxy config. I've got more than I show here, but this is the part that handles my main Solr index: http://apaste.info/0vk The ncmain core is a core that has no index, with the shards parameter built into the config, so the application has no idea that it's talking to a sharded index that actually lives on two separate servers. Thanks, Shawn
