因为公司有专用代理服务器，所以客户端不需要缓冲IE网页。这样还能减少病毒感染的机会。
默认活动目录组策略里是没有这个功能的， 所以我们单独写一个文件并保存为策略文件如下。
然后打开要应用的组策略展开User Configuration ,右键单击Administrative Templates 然后选添加删除模板，点添加然后找到我们制作的IE_Cache_Setting.adm模板添加并关闭窗口。

展开：User Configuration > Administrative Templates > Windows Components > Internet Explorer > Cache 可以看到里面多了配置IE 缓存的选项，按需要设置即可。

请用记事本编辑文件内容如下并保存为管理模板文件名：IE_Cache_Setting.adm
