asp.net mvc - How do I specify a return url for a link to the login form? -

It appears to be quite simple, but it did not come out - mainly because of the fact that the view can not possibly be known Even if you go through which model and controller there, this is a problem which needs solutions:

I have a login link, which will allow the user to enter the user name and password. takes away. When the user clicks on "submit", I want to redirect to the page he was looking at. The easiest way to do this is to specify the URL as the current page in the form of a page ( ... ... returnUrl = ... ) and everything else has already been made .

But when I consider the URL, from where I think this URL should be used? I can not use a RedirectToActionResult naturally because I do not really want to transfer the user - how to present the URL in only one link?

Edit:

I have now started a reward on this question, and so I am fit to clarify my needs too.

Login to my shared folder is a UserControl named .ascx. In it, I present an application link in the login form, and it is included in the footer on my masterpage. What I want to accomplish is the following:

When ActionLink is provided, the querystressing returnUrl is added to with this view that is currently presented Is being done . If it is complete, the user will be taken back to the page that was looking after a successful login with the functionality that is already built in the ASP.NET MVC framework.

The reason for past replies is adequately enough that they have not provided a way to create the Root URL for the current view I know that How to add a query string, but I do not know what to put in that string.

To mark the answer as as an answer, I want a method to rebuild the path in the scene currently shown, in the masterpage From user control

The solution is to use HttpContext.Current.Request.RawUrl:

  & lt;% = Html.ActionLink ("Log on", "Login", new {controller = "user", ReturnUrl = HttpContext.Current.Request.RawUrl})%>  

Or (with Microsoft.Web.Mvc.dll) with an extension method:

  & lt;% = HTML.ActionLink & lt; AccountController & gt; (C = & Gt; c.LogOn ("name", "password", false, http console. Current request request URL), "login here")% & gt;  

The default in the action controller MVC, but just add the return URL to your own.
