Nginx cache configuration and update cache, negotiation cache

General cache configuration example

# 静态文件

  expires 20d;
  access_log off;
}
location ~ ^/web/.*\.(js|css)?$ {
    
    
  expires 7d;

Example for Configuring the Negotiation Cache

Solved the problem that static resources are not updated after modification

  # 公共静态页面
location / {
    
    
  add_header Cache-Control no-cache; # 加上这个响应头，表示协商缓存，解决了静态资源修改后不更新的问题
  index index.html index.htm;
}
