Nginx cache static files (such as CSS JS) __js

Purpose: To cache the static files of the Nginx server. As css,js,htm,html,jpg,gif,png,flv,swf, these files are not updated frequently. Easy caching to ease server pressure.
Implementation: Nginxproxy_cache can cache the user's request to a local directory, when the next request can be directly transferred to the cache file, you do not have to go to the backend server to fetch files.
Configuration: Open configuration file/etc/nginx/nginx.conf
