Nginx Complete Configuration File Example

Example one:

This is a more complete example of nginx configuration file, the following nginx.conf simple implementation of nginx in the front-end to do reverse proxy server example, processing JS, PNG and other static files, JSP and other dynamic requests forwarded to other server Tomcat, as well as load-balanced configuration.
