When I POST to a page using the following code, Response.write (“Hey”) does not write the content (“Hello”) to the parent page
<form method="post" name="upload" enctype="multipart/form-data"
action="http://localhost:2518/Web/CrossPage.aspx" >
<input type="file" name="filename" />
<input type="submit" value="Upload Data File" name="cmdSubmit" />
</form>
But when I use the following code and POST data, Response.write ("Hey") can be obtained on the parent page
HttpWebRequest requestToSender = (HttpWebRequest)WebRequest.Create("http://localhost:2518/Web/CrossPage.aspx");
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 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 have no code in the Page_Load event of the parent page.?
What could be the reason? I need to write “hey” on the parent page using the first script. Both applications have a different domain.
Edit: "Hello" will be from CrossPage.aspx. I need to write this to the parent page
, Page_Load() CrossPage.aspx, URL " http://localhost:2518/Web/CrossPage.aspx", , CrossPage.aspx .
