Uses for MachineKey in ASP.NET
Uses for MachineKey in ASP.NET
回答1
MachineKey is used for:
- ViewState encryption and validation
- Forms Authentication (or Federated Authentication) uses this key for signing the authentication ticket
Having a Web App installed on multiple servers requires same Machine Key configured on all of them in order for Load Balancing to work.
To see all details, please refer to: MSDN How To: Configure MachineKey in ASP.NET 2.0

Machine key is also used to encrypt/decrypt the webresources.axd parameters.
Even on a single server the machine key should be configured, because any recycle of the app domain will generate a new key when it is set to auto. This causes the next postback just for pages rendered before the recycle, to cause a viewstate validation error, and also issues with the resources during that time.
