Asp.net viewstate MAC验证在2台服务器上失败

Hy 我的.net应用程序应该使用负载平衡器ARR 2.0在2台服务器上运行

当我同时打开两台服务器时，会出现错误

System.Web.HttpException: Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. ---> System.Web.UI.ViewStateException: Invalid viewstate.
