基本上，我正在针对不同版本的 IE 优化网站。我正在使用 IE9(通过 IE 的关于页面验证)。
本地(使用 xampp)网站正确检测到浏览器是 IE9 并加载正确的 css 代码。但是，当我将代码放到文本服务器上时，它会将浏览器视为 IE7。
对于测试:
我使用 xmapp 在本地获得的输出
According to the conditional comment this is IE
According to the conditional comment this is IE 9
According to the conditional comment this is IE 8 or higher
According to the conditional comment this is IE greater than 6
我在测试服务器上得到的输出:
According to the conditional comment this is IE
According to the conditional comment this is IE 7
According to the conditional comment this is IE lower than 9
According to the conditional comment this is IE lower or equal to 7
According to the conditional comment this is IE greater than 6
关于问题可能是什么的任何想法？
