Nginx configuration, expiry headers and gzip component with rails – nginx.conf
Just configured nginx server with rails and here is the nginx.conf file. It also includes gzip component and header expiry which is advisable as per the yslow tool.
# user and group to run as
# number of nginx workers
worker_processes 4;
# pid of nginx master process
#pid /var/run/nginx.pid;
# Number of worker connections. 1024 is a good default
events {
worker_connections 1024;
}
# start the http module where we config http access.
http {
# pull in mime-types. You can break out your config
# into as many include’s as you want to make it cleaner
include mime.types;
# set a default type for the rare situation that
# nothing matches from the mimie-type include
