How can I tell if my controller action is being called from another controller action?

Is there any easy way to distinguish between an ASP.NET MVC controller action being hit "directly" due to a client web browser request, and being hit by virtue of a Controller.RedirectToAction call or a RedirectToRoute result?

Alternatively, put a value in TempData

public class SomeController : Controller
{
    public ActionResult SomeAction()
    {
        // ... do stuff ...
        TempData["SomeKey"] = "SomeController.SomeAction";
        return RedirectToAction("SomeOtherAction", "SomeOtherController");
    }
}

public class SomeOtherController : Controller
{
    public ActionResult SomeOtherAction()
    {
        if (TempData.ContainsKey("SomeKey"))
        {
            // ... do stuff ...
        }
        // etc...
    }
}

You may have the option of adding a parameter to your Action method that allows you to pass in a value specifying whether it's a Controller.RedirectToAction, a RedirectToRoute, or a client browser request. Couple this with some server variable checks and you may be able to come up with something that works most of the time.

public ActionResult MyAction(string source)
{
    if (source == "")
    {
        // client browser request
    }
    else if (source == "redirectToAction")
    {
        // redirect to action
    }
    else if (source == "redirectToRoute")
    {
        // redirect to route
    }
}

Request.ServerVariables["http_referrer"] would be empty if is the action is hit from a redirect to action, I think. Otherwise it would be the URL that corresponds to the action method visited "directly".
