系统做迁移，在新服务器IIS上部署，部署后的系统在IE8和其他浏览器上显示正常，
但是在IE11上显示错乱，并且还会出现"__doPostBack”未定义。
1.首先在原服务器又部署了一次，显示正常，排除代码问题和IIS(网站和应用程序池)问题。
2.怀疑IIS设置问题，所有设定参数都对比了一遍，设置基本一致。
3.代码增加IE7标准模式，未解决
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />
4.调试中出现"__doPostBack”未定义，根据这个错误百度出问题的真正原因，
服务器版的.Net40的补丁没有打上，ASP.NET 可能无法辨识出一些浏览器的最新版本
1）按照网友的方法，修改C:WindowsMicrosoft.NETFramework64v4.0.30319ConfigBrowsersie.browser，
也许可行，但是我这边不行

3)在网站目下，新建App_Browsers文件到，新建ie.browser文件，内容如下，问题得到了解决。
