ASP.NET忽略Web.config中的IE7兼容性模式标记 [英] ASP.NET Ignores IE7 Compatibility Mode Tag in Web.config

问题描述

我的Web.config文件中有以下部分

I have the following section in my Web.config file

<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>

但

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7"/>

不会出现在页面的标题中。我遵循这篇文章中的建议 ASP.NET应用程序 - 设置IE7兼容模式？ ，但它似乎没有按预期使用IE8和IIS6工作。任何提示？

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?

推荐答案

问题是我使用 IIS6 。 IIS6查看Web.config的< system.web> 部分，而不是< system.webServer> 部分（由IIS7使用，除非它以兼容模式运行）。要在运行IIS6时在网站的每个页面上呈现此元标记，我相信最好的选择是将其添加到您的MasterPage。我最后添加以下代码块到我的MasterPage的OnPreRender事件：

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:

Page.Header.Controls.AddAt(0, new HtmlMeta { HttpEquiv = "X-UA-Compatible", Content = "IE=EmulateIE7" });

我使用AddAt而不是简单的Add的原因是因为X-UA-Compatible元标签显然

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.

希望这可以帮助同一艘船上的某人！
