UrlActionResult in asp.net MVC

I want to know is there any open source action result code available for asp.net mvc in which i can pass a URL and it will response out the content.

Just like there are some inbuilt Action results

I want to build a custom Action Result in which i can pass a URL (basically an mp3 url) which will get downloaded in memory and the content will be streamed to the current executing response.

It should also support resume download if supported by server and client. Thats a must for me.

public UrlActionResult DownloadUrl(string url)
{
     return new UrlActionResult("http://www.example.com/audiofile.mp3");
}

If you don't need to hide the url just use a redirect. Using a redirect with spare you server bandwidth:

public ActionResult DownloadUrl(string url)
{
     return new Redirect("http://www.example.com/audiofile.mp3");
}

For a basic scenario you could use something like this:

public class DownloadResult : ActionResult
{
    private readonly FileStreamResult _fileStreamResult;

    public DownloadResult(string url, string contentType)
    {
        using (var myWebClient = new WebClient())
        {
            var myStream = myWebClient.OpenRead(url);
            _fileStreamResult = new FileStreamResult(myStream, contentType);
        }
    }

    public override void ExecuteResult(ControllerContext context)
    {
        _fileStreamResult.ExecuteResult(context);
    }
}

However if you want to do the resume download it becomes a lot more complicated. Here is a great article with example code.
