MVC 4 RedirectToAction没有看到自定义报头

如果你启动一个新的Web项目，并创建一个新的MVC4应用程序(子类型为"WebApi")，你可以粘贴下面的代码(覆盖homeconcontroller .cs)，以使代码工作。

我有一个MVC4应用程序(与WebApi)。

我试图在MVC控制器方法中设置一个自定义头，然后做一个RedirectToAction。在第二个mvc-controller-方法中看不到自定义头。

我可以在第一个mvc-controller-method中设置一个cookie，并在第二个mvc-controller-method中看到它(在RedirectToAction之后)。

是否有一种方法可以看到我在第二个mvc-controller-method中设置的自定义头RedirectToAction ?

谢谢。
