Hi,

I'm just starting to use the TestHelpers in MvcContrib. I want to try and test an action method on my controller that itself tests if IsAjaxRequest() is true.

I've used the same code that is shown in the TestHelper samples to set up the TestControllerBuilder

_controller = new StarsController();    
_builder = new TestControllerBuilder();
_builder.InitializeController(_controller);

So that _controller has all the faked/mocked HttpContext inside it, which is really great. But what do I do now to force IsAjaxRequest() on the internally faked Request object to return true?
