Answer 1

I suggest you to create an Action with form which receives a Model in parameters. Then, just pass model when you redirect to this Action

[HttpPost]
public ActionResult OrderSummary()
{
    return RedirectToAction("OrderForm", new { HashData = hashData });
}

[HttpGet]
public ViewResult OrderForm(string hashData)
{
    OrderFormModel model = new OrderFormModel();
    model.HashData = hashData;
    return View(model);
}

[HttpPost]
public ActionResult OrderForm(OrderFormModel model)
{
    if(ModelState.IsValid)
    {
        // do processing
    }
}

Answer 2

You cannot post a form by Redirect method. You could send generated form string to View and after that post the form by Javascript.

public ActionResult OrderSummary()
{
    string request=PreparePOSTForm("payment URL","hashdata required for payment")
    return View(model:request);
}

and in View of OrderSummary:

@model string

@Html.Raw(Model)

<script>
    $(function(){
       $('form').submit();
    })
</script>

Answer 3

You can do it with JavaScript.

Make a page which does have a html form and submit it through javascript and put your information as input:hidden in the form.

This will submit the data to the another place you want. Doing it in html gave you more control and you doesn't need to write a action like shown in other answer for every redirect in your app.
