HttpContext.Request.UrlReferrer

Answer 2

The best way is to simply pass this information to the controller action.

So for example you could include the request url as a hidden field:

<% using (Html.BeginForm("Process", "SomeController")) { %>
    <%= Html.Hidden("requestUrl", Request.RawUrl) %>
    <input type="submit" value="OK" />
<% } %>

and inside the corresponding controller action :

[HttpPost]
public ActionResult Process(string requestUrl)
{
    // requestUrl will contain the url of the page used to 
    // render the form
    ...
}

You could also use the controller and action from route data:

<% using (Html.BeginForm("Process", "SomeController")) { %>
    <%= Html.Hidden("controllerName", ViewContext.RouteData.GetRequiredString("controller")) %>
    <%= Html.Hidden("actionName", ViewContext.RouteData.GetRequiredString("action")) %>
    <input type="submit" value="OK" />
<% } %>

and both controllerName and actionName will be sent in the POST request.
