Example Configuration

gzip_static
The ngx_http_gzip_static_module module allows sending precompressed files with the “.gz” filename extension instead of regular files.//ngx_http_gzip_static_module//模塊允許發送擴展名爲.gz的預壓縮文件而不是常規文件。
This module is not built by default, it should be enabled with the --with-http_gzip_static_module configuration parameter.//這個模塊默認不會創建，他應該用–with-http_gzip_static_module配置參數啓用。
Example Configuration
gzip_static on;
gzip_proxied expired no-cache no-store private auth;
Directives
Syntax: gzip_static on | off | always;
Default:
gzip_static off;
Context: http, server, location
Enables (“on”) or disables (“off”) checking the existence of precompressed files. The following directives are also taken into account: gzip_http_version, gzip_proxied, gzip_disable, and gzip_vary.//啓動或者關閉通過檢查預壓縮文件的存在性，以下指令也被考慮在內
With the “always” value (1.3.6), gzipped file is used in all cases, without checking if the client supports it. It is useful if there are no uncompressed files on the disk anyway or the ngx_http_gunzip_module is used.//使用always這個值的時候，壓縮文件被用於任何情況，不用檢查客戶端是否支持。如果磁盤裏面沒有任何被壓縮過的文件或者ngx_http_gunzip_module模塊被使用，這將非常有用。
The files can be compressed using the gzip command, or any other compatible one. It is recommended that the modification date and time of original and compressed files be the same.//文件可以被gzip命令或者其他任何其他兼容的命令壓縮，推薦原始文件和修改文件的時間日期相同
