我有一个非常奇怪的问题，我无法弄清楚。我不确定它是怎么发生的。这仅在 IE 10 中发生（尚未尝试其他版本的 IE）。这在 Firefox、Chrome、Opera 或 Safari 中不会发生。当用户 1 登录网站时，他们也可以看到他们所属的商店。如果有 10 家商店并且他们只能访问 4 家，那么他们只会在下拉菜单中看到这 4 家商店。下拉列表是动态的，并从 SQL Server 表中接收值。如果用户 1 注销，他们会被发送到注销页面，该页面会放弃会话，将用户从表单身份验证中注销，然后将他们重定向回登录页面。现在，用户 2 登录。它转到“仪表板”，显示用户 2 已登录。当用户 2 导航到特定页面时，用户 2 用户名变为用户 1' s 用户名，然后用户 2 现在可以看到用户 1 所属的所有商店。离开此页面，将显示用户 2 的信息。导航回该特定页面，用户 1 又回来了。正如我之前所说，我不确定发生了什么。我什至不确定要向您展示什么代码。我会假设如果这是一个编码问题，它会在我的页面加载到那个特定的页面上。这是该网络表单的页面加载。它将在该特定页面上的我的页面加载中。这是该网络表单的页面加载。它将在该特定页面上的我的页面加载中。这是该网络表单的页面加载。

page_load 中发生了很多事情，但对我来说一切都很好。我正在通过 FormsAuthentication 使用 AD 身份验证（但我无法使用角色来允许特定用户查看某些信息）。我几乎把它归结为 IE，但该公司使用 IE 作为标准浏览器。有谁知道解决方案，或者看到我做错了什么？我忘了提到这发生在生产服务器和开发服务器上（仅在 IE 中），但在 IE 中的本地机器上调试不会导致问题。IIS 是 Server 2008 上的第 7 版。非常感谢任何建议。如果需要更多信息，请告诉我。
编辑：发生在 IE 9 和 11 上。如果我刷新有问题的页面，它工作正常。不太清楚发生了什么。
