客户端应用在我的aspx页面上的Response.Write（..）之后的同一会话中发送请求。 我可以检索这些数据吗？

Question

There are two web application.

WebApp1 send POST-request(1) to WebApp2. Then WebApp2 send POST-response(2) to WebApp1. I am developing WebApp2. I create simple aspx-page. OnLoad event give me ability to process (1) & (2) and provide app logic. To make response(2) I am using Response.Write(...). But! after response(2) WebApp1 send one more request to my app, to confirm, that my response recieved succesfully. That is the problem. I don't know how to catch (3). Response.Write(...) writes to response stream, but doesn't return any data from WebApp1.

    protected void Page_Load(object sender, EventArgs e)
    {

        if (Request.HttpMethod == "POST")
        {
            logger.Trace(" -- POST REQUEST ...");
            string requestBody;
            using (StreamReader writer = new StreamReader(Request.InputStream))
            {
                requestBody = writer.ReadToEnd();
                logger.Trace("Request body:\n{0}", XmlHelper.FormatStringToXml(requestBody));
            }
            string responseBody = ProcessRequest(requestBody);

            logger.Trace("Response body:\n{0}", XmlHelper.FormatStringToXml(responseBody));
            if (!string.IsNullOrEmpty(responseBody))
            {
                SendPostXmlResponse(responseBody);
            }
            else
            {
                logger.Error("Cant send empty response. No response was sended.");
            }
        }
        else
        {
            logger.Error(" -- GET REQUEST is not supported. No actions were made.");
        }
    }


    private void SendPostXmlResponse(string response)
    {          
        Response.ContentType = "text/xml";
        Response.Clear();
        Response.BufferOutput = true;
        Response.Charset = "utf-8";
        Response.ContentEncoding = System.Text.Encoding.UTF8;
        using (MemoryStream stream = new MemoryStream (SmsService.StringToUTF8ByteArray(response)))
        {
            stream.WriteTo(Response.OutputStream);
        }
    }

Method SendPostXmlResponse(string response) must return data, recieved from client, after response is sended.

The way you try to do it can not work because from the moment you start sending data, you can not stop sending and start reading again.

Its better to send a link to the other side with some code, and the other side replay to with a new call to this link as confirmation that get the data.

At the bottom, if after you send all your data this parametre is Response.IsClientConnected is true, then the data are there and the communication is not lost.
