ASP.NET MVC Login ReturnUrl always NULL?

Question

Using Forms Authentication in ASP.NET MVC when trying to log back into a site, it puts a ReturnUrl parameter in the query string. My Logon action method accepts a \"returnU

Answer 1

There are two ways I can think of to deal with logon and logoff scenarios. Dave Beer outlined one way, above. There is another approach that works in many situations. I used it when I coded the NerdDinner tutorial. The tutorial provides us with a logoff function that logs you off and takes you home. I did not want that. I wanted to return to the page I was on before I logged off. So I modified my Account controller logoff action to look like this

   public ActionResult LogOff()
    {
        FormsService.SignOut();
        return Redirect(Request.UrlReferrer.ToString());
    }

You can get fancier and pass in a returnUrl and test for it, in case you want to override this behavior. But I don't need that. This achieves the desired result. The Logon can work similarly. Maybe there are ways to use the MVC framework to do this for me, but until I learn them, this is VERY simple and works reliably.
