I would like to clarify some doubts I have about using nginx to proxy requests over a cluster of thin servers (http://code.macournoyer.com/thin/). I've read many blog posts about using UNIX sockets and not TCP connections, my only doubt is about multiserver configurations, where the cluster is spread on more than one machine, and the proxy acts as a frontend. How do I share UNIX sockets ? Should I share the directory that contains the .sock files or there's something I'm missing ? How do you guys handle this kind of deployment ?
