ASP.NET忽略IE7兼容模式标签在Web.config中 [英] ASP.NET Ignores IE7 Compatibility Mode Tag in Web.config

问题描述

我有以下的部分，我的Web.config文件

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"/>

不在的时候都在我的网站提供的页面的标题present。我跟着这个职位的建议<一href=\"http://stackoverflow.com/questions/713581/asp-net-app-set-ie7-compatibility-mode\">http://stackoverflow.com/questions/713581/asp-net-app-set-ie7-compatibility-mode但它不会出现要工作作为使用IE8和IIS6预期。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 http://stackoverflow.com/questions/713581/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

原来，问题是，我使用的 IIS6 。 IIS6着眼于＆LT;的System.Web＆GT; Web.config文件，而不是部分的＆LT; system.webServer＆GT; 部分（它是由IIS7使用的，除非它在兼容模式运行）。要在运行时IIS6渲染网站的每个网页上的这个元标记，我相信最好的选择是将其添加到您的母版。我最终加入以下code座我母版的在preRender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" });

我用AddAt，而不是只是简单的添加的原因是因为X-UA兼容meta标签显然已经是在页面头部的第一件事，以便它得到尊重。

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.

希望这可以帮助别人在同一条船上！
