Passing a model object to a RedirectToAction without polluting the URL?

asp.net-mvc-3, c#, controller, model

Solution

Sounds like a solution for TempData!

[HttpPost]
public ActionResult Index(ContactModel model)
{
  if (ModelState.IsValid)
  {
    // Send email using Model information.
    TempData["model"] = model;
    return RedirectToAction("Gracias");
  }

  return View(model);
}

public ActionResult Gracias()
{
  ContactModel model = (ContactModel)TempData["model"];
  return View(model);
}

Problem

Here's what I'm trying to do: ``` public ActionResult Index() { return View(); } [HttpPost] public ActionResult Index(ContactModel model) { if (ModelState.IsValid) { // Send email using Model information. return RedirectToAction("Gracias", model); } return View(model); } public ActionResult Gracias(ContactModel model) { return View(model); } ``` All three action methods are in the same controller. Basically, a user type up some data in the contact form and I want to redirect them to a thank you page using their name in the Model object. As the code is, it works, but the URL passed along with GET variables. Not ideal. ``` http://localhost:7807/Contacto/Gracias?Nombre=Sergio&Apellidos=Tapia&Correo=opiasdf&Telefono=oinqwef&Direccion=oinqef&Pais=oinqwef&Mensaje=oinqwef ``` Any suggestions?
