TempData not migrated during RedirectToAction

I have an interesting problem with an object TempDatanot passing values ​​to another controller.

I set TempData["Enroll"]in the method Enroll Controller HttpPostfor the model Enroll. Then I read the object TempData["Enroll"]in the method Register Controller HttpGet, but empty/ null.

I need to save all this data on three controllers.

Any thoughts?

Here is a snippet of code

EnrollController.cs
[HttpPost]
public ActionResult Index(EnrollModel model)
{
   ...
   TempData["EnrollModel"] = model;
   return RedirectToAction("Index", "Register");
}

RegisterController.cs
public ActionResult Index(string type)
{
    RegisterModel model = new RegisterModel();

    EnrollModel enrollModel = TempData["EnrollModel"] as EnrollModel;
    model.ClientType = enrollModel.ClientType;
    ...
}

I came across these limitations with TempData before. At best, I found it unrealistic and sporadic.
