.Net/Flex: How to read partial results from URLRequest?

I'm working on a batch process script that's executed from Flex. The batch script is in a .aspx Page and returns partial results through the following class:

public class ResponseLogger
{

    private HttpResponse _response;

    public ResponseLogger(HttpResponse response)
    {
        this._response = response;
    }

    public void Start()
    {
        _response.Clear();
        _response.ContentType = "text/plain";
        _response.ContentEncoding = System.Text.Encoding.GetEncoding("ISO-8859-1");
    }

    public void End()
    {
        _response.End();
    }

    public void Br()
    {
        Log("");
    }

    public void Underline(string message)
    {
        Log(message);
        Log("".PadLeft(message.Length, '-'));

    }

    public void Log(string message)
    {
        _response.Write(message + "\n");
        _response.Flush();
    }

}

In my Flex application I'd like to show the result as soon as it's flushed on server side. Can this be done using Actionscript?

Short answer, no, you cannot do partial results over HTTP unless you do short/long polling (several http calls per minute). HTTP in it's essence is a request-response protocol.

What you want is a push technology, but I'm not sure if there's a .NET equivalent for this. On the Java side you got BlazeDS or GraniteDS for push messaging.

The other question is why are you results 'partial'?
