Question

User-1166428634 posted

Hi All,

          I published my first web site. .... It is really good thing for me it is published World Wide Web. Sometime it give me below error :

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.

If I press F5 / Refresh then it goes well. But why it comes I don't understand... I also want to ask you if any kind of error 
occours at runtime my users really displike to see the YELOW PAGE HAVING RED ERROR MESSAGE.

How to ignore these kind of errors / exceptions?

Thanks
