Hello All,

When i POST the page using the following code, the Response.write("Hey") doesn't write the content ("Hello") to the parent page

<form method="post" name="upload" enctype="multipart/form-data"
action="http://localhost:2518/Web/CrossPage.aspx?cmd=getvalue" >
<input type="file" name="filename" />
<input type="submit" value="Upload Data File" name="cmdSubmit" />
</form>

But When i use following code , and POST the data, the Response.write("Hey") can be obtained in the parent page

 HttpWebRequest requestToSender = (HttpWebRequest)WebRequest.Create("http://localhost:2518/Web/CrossPage.aspx?cmd=getvalue");
 requestToSender.Method = "POST";
 requestToSender.ContentType = "multipart/form-data";

 HttpWebResponse responseFromSender = (HttpWebResponse)requestToSender.GetResponse();
 string fromSender = string.Empty;

 using (StreamReader responseReader = new StreamReader(responseFromSender.GetResponseStream()))
    {
        fromSender = responseReader.ReadToEnd();
    }

In the CrossPage.aspx i have the following code

 if (!Page.IsPostBack)
    {
        NameValueCollection postPageCollection = Request.Form;

        foreach (string name in postPageCollection.AllKeys)
        {
            Response.Write(name + " " + postPageCollection[name]);
        }

        HttpFileCollection postCollection = Request.Files;
        foreach (string name in postCollection.AllKeys)
        {
            HttpPostedFile aFile = postCollection[name];
            aFile.SaveAs(Server.MapPath(".") + "/" + Path.GetFileName(aFile.FileName));
        }

        Response.Write("Hey");
    }

I don't have any code in the Page_Load event of parent page.?

What could be the cause? I need to write the "hey" to the Parent page using the first scenario. Both the application are of different domain.

Edit: "Hey" would be from the CrossPage.aspx. I need to write this back to the Parent Page
