ASP.NET Ignores IE7 Compatibility Mode Tag in Web.config
提问by Chris Shouts
I have the following section in my Web.config file
我的 Web.config 文件中有以下部分
<system.webServer>
<!-- For now..... lets be safe and put IE8 in IE7 compatibility mode-->
<httpProtocol>
<customHeaders>
<clear />
<add name="X-UA-Compatible" value="IE=EmulateIE7" />
</customHeaders>
</httpProtocol>
</system.webServer>
but the
但是
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7"/>
is not present in the header of the pages when they are rendered on my site. I followed the advice in this post ASP.NET App - Set IE7-Compatibility Mode?but it does not appear to be working as expected using IE8 and IIS6. Any hints?
当它们在我的网站上呈现时，页面的标题中不存在。我遵循了这篇文章中的建议ASP.NET App - Set IE7-Compatibility Mode? 但使用 IE8 和 IIS6 时它似乎没有按预期工作。任何提示？

Turns out the problem was that I'm using IIS6. IIS6 looks at the <system.web>section of Web.config instead of the <system.webServer>section (which is used by IIS7, unless it's running in compatibility mode). To render this meta tag on every page of your site when running IIS6, I believe the best option is to add it to your MasterPage. I ended up adding the following code block to the OnPreRender event of my MasterPage:
原来问题是我使用的是IIS6。IIS6 查看<system.web>Web.config 部分而不是<system.webServer>部分（IIS7 使用的部分，除非它在兼容模式下运行）。要在运行 IIS6 时在站点的每个页面上呈现此元标记，我相信最好的选择是将它添加到您的 MasterPage。我最终将以下代码块添加到 MasterPage 的 OnPreRender 事件中：
Page.Header.Controls.AddAt(0, new HtmlMeta { HttpEquiv = "X-UA-Compatible", Content = "IE=EmulateIE7" });
The reason I used AddAt instead of just plain Add is because the X-UA-Compatible meta tag apparently has to be the first thing in the page header in order for it to be respected.
我使用 AddAt 而不是简单的 Add 的原因是因为 X-UA-Compatible 元标记显然必须是页眉中的第一件事，才能使其受到尊重。
Hope this helps someone in the same boat!
希望这可以帮助同一条船上的人！
