我的ASP.NET Core 1.1.1应用程序在大约 30 分钟后退出。我正在使用一些会话变量，并且已经安装Microsoft.AspNetCore.Session package并配置了应用程序，如下所示。已将会话到期时间设置为 2 小时。从我读到的 Authentication Cookie 时间默认为 14 天，所以这应该不是问题。问题：看来我可能在这里遗漏了一些东西。需要做什么才能让应用在 2 小时前不注销？可能的原因是什么，可能的解决方案是什么？

注意：该应用程序正在运行IIS 10 on windows 10。该应用程序的应用程序池设置为Not Managed Code，默认空闲超时为 20 分钟，空闲 timtout-action 设置为Terminate。但据我所知，IIS 应用程序池空闲超时设置在 ASP.NET Core 中没有任何作用。
