如果您的服务器作为集群的一部分运行（即对您的应用程序的请求在多个服务器之间平衡），您必须确保您的机器都配置为使用相同的机器密钥。

发生回发时，ASP.NET 会验证 ViewState 数据。此验证使用私钥（机器密钥）来保证数据的完整性。如果您没有明确指定此密钥，则会为您生成它。不同的机器会生成不同的密钥，因此负载均衡的请求可能会验证失败，因为它们根据页面的首次提供位置和回发的发回位置对不同的密钥进行验证。

本文将向您详细介绍机器密钥的用途以及如何配置您的服务器。

您需要在所有服务器上的 web.config 中拥有相同的验证密钥。

您可以在此站点的帮助下生成密钥

请同时检查您的 IIS。在连接部分，显示应用程序池列表中，选择预期的池并转到“回收...”工具菜单。确保分配了足够的内存。要查看这一点，请在安装 IIS 的计算机上的任务管理器中观察 w3wp.exe 进程使用的内存量。正确设置回收管理器属性。我放弃了“虚拟内存使用”复选框，并更愿意为回收池应用程序计划指定的时间。
