Cache static files in nginx (such as css js)

Objective: To cache static files on the nginx server. Such as CSS, JS, htm, HTML, JPG, GIF, PNG, FLV, SwF, these files are not updated frequently. It is easy to cache to reduce the pressure on the server.

Implementation: nginxproxy_cache can cache users' requests to a local directory. When the next request is sent, the cached files can be directly retrieved, so that the files do not need to be retrieved from the backend server.

Configuration: Open the configuration file/etc/nginx. conf.
