Web Performance Tests and View State in Visual Studio

Hello,

I have recorded a Web Performance Test in Visual Studio on a localhost website (ASP.NET Webforms), this allows me to have the WebServer/domain as a variable so I can switch the test between localhost, or a staging environment for example.  Unfortunately the test has ViewState data in the form POST calls and this results in a viewstate failure when I run it anywhere other than local.  I understand why this gives us a viewstate problem and how viewstate works, what I am looking for is someone that knows if and how I can use the Performance Tests against multiple environments.

Thanks!
