Preventing multiple plug-in request calls with IsRedirectFollow()

Figured I'd share something I found valuable.  Did you ever make a call to a request level plug-in in a Visual Studio 2008 WebTest and get multiple calls to the same plug-in because of a 302 redirect?  Well I did and took me a little bit to find out a way to prevent it.
When you are making the call in your code, decide if it should run based on IsRedirectFollow property (http://msdn.microsoft.com/en-us/library/microsoft.visualstudio.testtools.webtesting.webtestrequest.isredirectfollow(VS.80).aspx)
As an example:

  1: namespace MyAppTests
  2: {
  3:     public class GetSomethingPlease: WebTestRequestPlugin
  4:     {
  5:         
  6:         public override void PostRequest(object sender, PostRequestEventArgs e)
  7:         {
  8:             if (e.Request.IsRedirectFollow == false) //only want to run this on on a primary, not a redirect
  9:             {
 10:                 //do something here
 11:              }
 12:          }
 13:       }
 14: }
 15: 

Anyway, I hope this helps someone else a little further along.  It works in VS2008 and VS2010 as well.  I'm sure there could be a more efficient way, but this worked in a pinch ;-)
