asp.net - 在 IIS 7 中使用 session 时出错

Question

将我的网站部署到 IIS 后，我在尝试访问 session 时收到以下错误消息:

Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration.

我在 Page_Load 或 PreRender 事件中访问它(我尝试了这两个版本)。使用 Visual Studio Dev Server 可以毫无问题地工作。我尝试了 InProc 和 SessionState 存储、1 个和多个工作进程。我明确地向我的网页添加了 enableSessionState = "true" 。这是web.config的一部分:

</system.web>

我还需要做什么才能使其正常工作？

我尝试监视 IIS 是否使用 Process Monitor 访问 aspnet_client 文件夹并且没有获得任何访问权限。

这个解决方案恰好很好奇。虽然错误描述中的 IIS7 jn WIndows 2008R2 说要将 SessionStateModule 添加到 system.web 部分，但应该将其添加到 system.webServer 部分。

<system.webServer>
    <modules>
        <remove name="Session" />
        <add name="Session" type="System.Web.SessionState.SessionStateModule, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
    </modules>
</system.webServer>
