我有一个 Internet 应用程序,因此 IE9 默认位于兼容性视图中。我用X-UA-Compatible
国旗。我在 HTTP 标头和元标记中发送它。IE9 似乎接受它并使用 IE9 渲染引擎。但它仍然总是发送 IE-7 UserAgent 字符串。
有没有办法避免它,或者将这个 IE9 识别为非 IE7 浏览器?
我真的不想使用浏览器的白名单,而是使用不支持的浏览器(IE 5、6、7 和 8)的黑名单。
我的例子:
我正在打开页面,所以 IE9 正在发送一个 GET 请求:
GET http://myserver/mypage/ HTTP/1.1
Accept: application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*
Accept-Language: de-CH
User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/5.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; InfoPath.3; .NET4.0E)
Accept-Encoding: gzip, deflate
Connection: Keep-Alive
Host: myserver
Cookie: MAKEBROWSERTEST=true
然后,我的服务器正在回答:
HTTP/1.1 302 Found
Cache-Control: private, no-cache="Set-Cookie"
Content-Type: text/html; charset=utf-8

<html><head><title>Object moved</title></head><body>
<h2>Object moved to <a href="/myserver/mypage/two">here</a>.</h2>
</body></html>
IE9 正在重定向,但仍发送 MSIE 7.0 用户代理:
GET http://myserver/mypage/two HTTP/1.1
Accept: application/x-ms-application, image/jpeg, application/xaml+xml, image/gif, image/pjpeg, application/x-ms-xbap, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*
