I have a webfarm where the load balancer is not enforcing stickyness due to this I get occasional errors "Unable to validate data." I believe this is the view state and I have tried several things to reduce this error I have
1. Set the Viewstatmac to use the same SHA1 key on all machines in WebConfig
2. Set The Viewstatmac to be disabled in WebConfig
l3. astly I just disabled the viewstate in WebConfig using
<pages enableViewState="false" enableViewStateMac="false" />
each method yeilded the same amount of occasional errors. Does Viewstate implemented on page level override the application level.
Suggestions on resolving this problem are greatly appreciated.
