Question

我无法在ASP.Net应用程序中使Session State正常工作。我在所有EnableSessionState="true"指令中都设置了<%@ Page %>，但我似乎仍然在每个页面上发出不同的会话ID。

我正在使用Master Page，我无法找到指定EnableSessionState的方法（我假设如果使用它的Page有会话状态那么它呢？）

我在我的Web.config中设置<sessionState>元素以使用带有cookie的InProc会话状态但这似乎没有效果 - 我正在运行IIS 7所以我希望<system.web>要忽略的部分有利于<system.webServer>部分，并且在此中似乎没有用于会话状态的等效配置元素（或者它不是很明显）。

我已经尝试使用谷歌搜索这些东西，但我似乎无法找到能够解释我需要做什么才能在我的整个应用程序中启用会话状态并正常工作的东西。任何人的想法？

我的Web.config文件如下所示，如果需要，我可以发布更多详细信息。

在有人嘲笑我在AppSettings中存储数据库设置之前我应该指出，在生产中我会加密<appSettings>部分，并且数据库帐户只使用（并且需要）特定的特定权限数据库中。

Answer 1

设置 EnableSessionState = true并没有真正实现，默认情况下它在应用程序范围内。为确保IIS7配置正确，您可以尝试执行以下command：

appcmd set config /commit:WEBROOT /section:sessionState /mode:InProc

如果您在每个页面上看到一个新的SessionID，可能只是您的客户端没有存储/转发会话cookie（可能是因为浏览器的安全限制）。首先验证您确实正在呈现会话cookie，并且所有请求都是从同一域提供的。

要验证它不是cookie问题，您可以切换会话状态以使用cookieless模式查看后续请求中是否加载了正确的会话：

<sessionState cookieless="UseUri" />

Answer 2

我正在检查 Web.Config 中的会话状态参数。我相信有一个拼写错误。请再次验证web.config并测试.....

在 SessionState 标记中，无Cookie 属性仅接受“true”或“false”的值，但是您的web.config显示为“UseCookies”

<sessionState mode="InProc" timeout="20" cookieless="UseCookies" />

请将cookieless的值设置为false或true，然后重试。希望这会解决问题....

ASP.Net会话状态未正确启用
