title: ViewState and Web Load Testing
body: <p>I'm trying to do load testing against an ASP.NET web site and I need to be able to parametertise field value of a page to test different code paths.</p>
  
  <p>I had great success with JMeter when load testing a JSP web site before. However, because ASP.NET encodes all form values in the ViewState, changing control values does not really work. </p>
  
  <p>I Googled this problem and people said the web testing tool in Visual Studio Team Tester Edition works well with ASP.NET pages. However, it cost quite a bit so I am just wondering does anyone know how to get around the ViewState issue with JMeter or WAPT?</p>
