Dowload File

[rony_16]

Hi,
I have problem with downloading a file using WebRequest and
HttpWebResponse.
Inorder to download this file i need to call to url that tells to
prepare the file for download,
and then i call to another url that downloads the file.
I have a problem with that because:

1. i do not know when the server finished the preparetion.
2.i checked the HttpStatusCode but he doen't changes
(myresponse.StatusCode).

the problem causes the application to download only a part of the file
and that because the server hasn't prepared the file yet.
if i give him Thread.Sleep(100000) i do get the full file, but the file
can be 100Mb and 10sec won't help.

the code is:
//Preparing the file todownload...
//---------------------------------------------------------------------------------------------------------
HttpWebRequest webRequest3 = WebRequest.Create(d1) as
HttpWebRequest;
webRequest3.KeepAlive = true;
webRequest3.Headers.Add("Keep-Alive", "300");
webRequest3.Headers.Add("Accept","text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5");
webRequest3.Headers.Add("Accept-Language",
"en-us,en;q=0.5");
webRequest3.Headers.Add("Accept-Encoding", "gzip,deflate");
webRequest3.Headers.Add("Accept-Charset",
"ISO-8859-1,utf-8;q=0.7,*;q=0.7");

webRequest3.CookieContainer = cookies;
HttpWebResponse myResponse3 =
(HttpWebResponse)webRequest3.GetResponse();

Thread.Sleep(10000);
Stream ReceiveStream3 = myResponse3.GetResponseStream();

//-----------------------------------------------------------------------------------

//Downloading ....
//--------------------------------------------------------------------------------------
Console.WriteLine("Connecting to download link...");
HttpWebRequest webRequest2 = WebRequest.Create(re) as
HttpWebRequest;
webRequest2.ContentType =
"application/x-www-form-urlencoded";
webRequest2.KeepAlive = true;
webRequest2.CookieContainer = cookies;
HttpWebResponse myResponse2 =
(HttpWebResponse)webRequest2.GetResponse();
Stream ReceiveStream2 = myResponse2.GetResponseStream();
Console.WriteLine("Downloading...");

Common.SaveStreamToFile(@"C:\scrapingtest\file.csv ",
ReceiveStream2);
Console.WriteLine("Done Downloading");

Thanks, Rony
