I'm new to Nginx and the technology in general. I have spent some time on nginx.org. The one thing I'm not sure of is if I need to configure my web server, which is Thin (ruby), with sockets or should TCP be enough. The reason I ask is because a number of tutorial and blog posts seem to say that the two servers can communicate via tcp but at the same time most setups seem to be done with sockets.

I'm looking for Nginx to serve static files, specifically media files, but not anything that resides in my site's public folder. Anyway, to repeat, do I need sockets set up or should tcp be enough. So far tcp has not worked for me. Thanks for any advice , direction.
