I Frequently Get this Error In My Website..

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.

Also Session TimeOut very Quikly although I Have Set session Timeout =30 minutes in webconfig.
Plese Reply A Suitable Solution...It is Urgent..

Thanks & Regards,
Alokssm
