Question

Let’s say I have a simple ASP MVC3 list controller, with an add method, with an id parameter.

List:

http://localhost/MVCAPP/ListFoo/

Add method

http://localhost/MVCAPP/ListFoo/Add?id=1

In my Add method, I update my Viewmodel with the added element, then makes a call to:

return View("ListFoo", viewModel);

The updated list is displayed, and everything’s almost fine.

The problem is that with such a return, the URL in the address bar is still

http://localhost/MVCAPP/ListFoo/Add?id=1

And if the user hits F5, another item will be added, which I’d like to prevent.

I know I can filter out such a behavior in the controller, but I’d rather prefer to redirect the browser address bar to:

http://localhost/MVCAPP/ListFoo/

Do you know any way to do this?

By the way, I’m not sure trying to control the address bar content is the right way to look at this issue…

Answer 1

Use the Action.RedirectToAction method to redirect the client after the work is done in the controller.

Besides that, you could use POST as FormMethod to send data to the server.
