Question

我已在我的网络应用程序中处理了跨站点请求伪造。我将Page.ViewStateUserKey设置为令牌，每次我都会对此进行验证。

一切正常。但当有人试图攻击应用程序时，我在页面上收到此错误。

Server Error in '/' Application.
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

因此，每当发生此错误时，我想将页面重定向到某个错误页面。我无法做到这一点，请帮助我。

完整例外消息：

Server Error in '/' Application.
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.
