Hi,
I have controller say ControllerA with a ActionResult XYZ that creates a list of employee and stores it in TempData["EmployeeDetails"] and then redirects to the corresponding view. The View(XYZ) has a link that redirects to another ActionResult ABC, which displays the list.

public XYZ(int EmployeeDOB)
{
   //Creates a List based of same Date Of Birth
   TempData["EmployeeList"] = lstEmployee;
   return View();
}

In the view XYZ is a form dat takes the input EmployeeDOB which later redirects to another View ABC that displays the main List.

public ActionResult ABC()
{
  List<Employee> lstEmployeeDetail = TempData["EmployeeList"] as List<Employee>();
  //Display the result
}

At my localhost the code works fine the list is viewed correctly, but on the production site due to "https" the TempData returns as null.
How to resolve this issue???
