禁止web页面浏览器缓存

通过 html 标签设置 cache-control

不推荐，不靠谱

  <meta http-equiv="Pragma" content="no-cache" />  
  <meta http-equiv="Expires" content="0" /> 
  <meta http-equiv="Cache-Control" content="no-cache" /> 

通过nginx设置

location / {
    root **;  
    # 配置页面不缓存html和htm结尾的文件
    if ($request_filename ~* .*.(?:htm|html)$) 
    {
        add_header Cache-Control "private, no-store, no-cache, must-revalidate, proxy-revalidate";
    }
    index  index.html index.htm;
}
