我通过Nginx提供单页JavaScript应用程序,当我部署新版本时,我想强制浏览器使其JS缓存无效,并请求/使用可用的最新版本.

因此,例如,当我使用名为my-app-eaea342.js的文件替换服务器文件夹中名为my-app-8e8faf9.js的文件时,我不希望浏览器将my-app-8e8faf9.js从他们的缓存已经不再了但是当没有新版本可用时,我仍然希望他们从缓存中读取资产.

如何使用Nginx配置实现？这是我现有的配置：

server {
  listen 80;

  server_name my.server.com;

  root /u/apps/my_client_production/current;
  index index.html;

  # ~2 seconds is often enough for most folks to parse HTML/CSS and
  # retrieve needed images/icons/frames,connections are cheap in
  # Nginx so increasing this is generally safe...
  keepalive_timeout 10;
  client_max_body_size 100M;

  access_log /u/apps/my_client_production/shared/log/Nginx.access.log;
  error_log /u/apps/my_client_production/shared/log/Nginx.error.log info;

  location / {
    try_files $uri $uri/ =404;

    gzip_static on;
    expires max;
    add_header  Cache-Control public;

  }

  # Error pages
  error_page 500 502 503 504 /500.html;
}
