Validation of viewstate MAC failed.Application hosted by a Web Farm, ensure <machineKey> configuration
提问by Mitesh Jain
net 4.0 frame work, I had made many website in this frame work but never get such error
net 4.0 框架工作，我在这个框架中制作了很多网站，但从未出现过这样的错误
"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."
I think so this error is caused because of use of cookies as only in this website i had made use of cookies.
我认为这个错误是由于使用 cookie 造成的，因为我只在这个网站上使用了 cookie。
Another one thing i used to get this error very rarely almost 2twice a week

I had read many solutions for this but very rarer for 4.0
我已经为此阅读了很多解决方案，但对于 4.0 来说非常罕见
solution readed such as putting
解决方案读取，如放置
<machineKey validationKey="6628ECBFB40F6F852AB543C23C0B83C1679C5AAE35AD72FACF5B9F4FDB70AA1F648A1D5877CE1F9D69F08BAD919BFBAC0976D9119B8F32CFB80814E4E943F8EE" decryptionKey="42F45B378301126EB4CCBA16995304263754EF116E08A81003A936CC04B7537F" validation="SHA1" decryption="AES" />

you can add your machine key in system.web element. for e.g.
您可以在 system.web 元素中添加您的机器密钥。例如
<system.web>
<machineKey validationKey="1234567890123456789012345678901234567890AAAAAAAAAA"
decryptionKey="123456789012345678901234567890123456789012345678"
validation="SHA1" decryption="Auto" />
</system.web>
If you don't want to put a machinekey in the web.config for each application, you need to put it in machine level web.config for each .Net Framework version.
如果您不想在每个应用程序的 web.config 中放置 machinekey，则需要将其放置在每个 .Net Framework 版本的机器级 web.config 中。
