IIS7 GZIP压缩 - httpCompression部分

Question

我试图httpCompression在IIS7 上配置.通过谷歌搜索,我发现它可以使用httpCompression配置中的部分.问题是,我无法通过web.config使其工作.

当我applicationHost.config根据需要在一切工作中进行配置时,我希望能够为每个应用程序而不是全局进行此配置.

我在改款的定义applicationHost.config,以<section name="httpCompression" overrideModeDefault="Allow" />和移动httpCompression部分的web.config:

<httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
      <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" />
      <staticTypes>
        <add mimeType="text/*" enabled="true" />
        <add mimeType="message/*" enabled="true" />
        <add mimeType="application/x-javascript" enabled="true" />
        <add mimeType="application/atom+xml" enabled="true" />
        <add mimeType="application/xaml+xml" enabled="true" />
        <add mimeType="*/*" enabled="false" />
      </staticTypes>
      <dynamicTypes>
        <add mimeType="text/*" enabled="true" />
        <add mimeType="message/*" enabled="true" />
        <add mimeType="application/x-javascript" enabled="true" />
        <add mimeType="application/json" enabled="true" />
        <add mimeType="application/json; charset=utf-8" enabled="true" />
        <add mimeType="*/*" enabled="false" />
      </dynamicTypes>
    </httpCompression>  

我错过了什么？看起来IIS根本没有从web.config读取压缩配置.

每次更改后,我都会使应用程序池回收,所以这不是问题.

根据此ServerFault答案:https://serverfault.com/a/125156/117212 - 您无法在web.config中更改httpCompression,它需要在applicationHost.config文件中完成.以下是我在Azure Web角色中使用的代码,用于修改applicationHost.config文件并添加用于压缩的mime类型:

using (var serverManager = new ServerManager())
{
    var config = serverManager.GetApplicationHostConfiguration();
    var httpCompressionSection = config.GetSection("system.webServer/httpCompression");
    var dynamicTypesCollection = httpCompressionSection.GetCollection("dynamicTypes");

    Action<string> fnCheckAndAddIfMissing = mimeType =>
    {
        if (dynamicTypesCollection.Any(x =>
        {
            var v = x.GetAttributeValue("mimeType");
            if (v != null && v.ToString() == mimeType)
            {
                return true;
            }

            return false;
        }) == false)
        {
            ConfigurationElement addElement = dynamicTypesCollection.CreateElement("add");
            addElement["mimeType"] = mimeType;
            addElement["enabled"] = true;
            dynamicTypesCollection.AddAt(0, addElement);
        }
    };

    fnCheckAndAddIfMissing("application/json");
    fnCheckAndAddIfMissing("application/json; charset=utf-8");

    serverManager.CommitChanges();
}

ServerManager来自Microsoft.Web.AdministrationNuGet的包装.
