Redirect / show view after generated file is dowloaded

Question

I\'ve got a controller action that downloads a dynamically generated file:

    public ActionResult DownloadFile()
    {
        var obj = new MyClass { MyStr         


        

Answer 1

As Ross has said, you can only return one response to a HTTP request. What i do in that case is:

1. Send the request to the server
2. The server generates the file and stores it in some server side data structure (Cache, Usersession, TempData)
3. The server returns a RedirectToAction() (POST, REDIRECT, GET pattern)
4. The redirected action returns a View with some javascript which
5. Triggers the download of the pregenerated file by setting window.location.href property to an special download action which sends the file back to the browser
