Redirect after EndInvoke in ASP.NET MVC

Hi have the following code on my view (JQuery):

$.post('<%=Url.Content("~/Customer/StartLongRunningProcess")%>');

Wich invokes an asynchronous call (C#):

public void StartLongRunningProcess()开发者_如何学运维
    {

        ProcessTask processTask = new ProcessTask();
        processTask.BeginInvoke(new AsyncCallback(EndLongRunningProcess), processTask);
    }

Finally, the result of the call:

public void EndLongRunningProcess(IAsyncResult result)
    {
        ProcessTask processTask = (ProcessTask)result.AsyncState;
        string id = processTask.EndInvoke(result);


        RedirectToAction("~/SubscriptionList/SubscribedIndex/" + id);
     }

The redirect is ignored. Response.Redirect also fails, since the HTTP headers has been already sent. I've tried change the window.location from javascript, this works, but I'm unable to pass the parameter id by ViewData. Any idea to resolve this?

Are you sure the headers have already been sent? I'm not really up on asynchronous controllers, but I would doubt that it would start sending any headers right away. My first thought would be that a redirect response to an ajax call isn't handled by the browser. You will probably need to implement some logic that sends back a result with the URL and have your success delegate in jQuery look for that piece of data and then do the redirect through javascript (i.e. window.location).
