HttpContext.Current.User.Identity.Name 丢失答案

【问题描述】：

我在我的 Web 应用程序中使用 ASP.NET 表单身份验证。最近我发现了一个奇怪的行为。在生产环境中一切正常。使用 .net 4.0 和 IIS 7。在登录用户中输入用户名和密码并登录然后突然HttpContext.Current.User.Identity.Name 丢失。这不会每次都发生，只是在某些情况下。我无法在我的开发环境中重现该问题。我检查了if(HttpContext.Current.User.Identity.IsAuthenticated) 这也是真实的身份验证票用户数据也不为空。只有HttpContext.Current.User.Identity.Name 是空的。请帮助

登录按钮中的代码

【解决方案1】：

您的会话时间限制为 60 分钟。问题只发生在会话过期的人身上吗？可能会解释为什么您不能在您的开发机器上重现它，因为您根本不需要等待那么久？
