Cannot get request third time in a row - GetRequestStream() -

[Piotrekk]

Hi

I am uploading files to my ASP script one by one - from C#
application. Each time little upload form is created with
backgroundworke r in it. When I try to upload THIRD file the worker is
stuck on getting requeststream.


WebRequest req = WebRequest.Crea te(url);
req.Method = "POST";

//Headers
req.ContentType = "multipart/form-data";
req.ContentLeng th = fileSize;
req.Headers.Add ("Name",file.Na me);
req.Headers.Add ("Path", path);
req.Headers.Add ("SessionID" , session);

/// stuck here
Stream stream = req.GetRequestS tream();

When I debug it on the server during third time, the Page_Load event
is not even called.
Do you have any idea what could that be?

Best Regards
PK

Yes. Chances are you're not closing the response, which means the
connection to the server is left up, and you're only (by default)
allowed two connections to any one server.

Where you fetch the response, put it in a "using" statement and chances
are it'll all start working with no issues.

Dear Jon. I'm not using response in my connection. Here is the entire
backgroundworke r code:


string url = String.Concat(t his.url);
long fileSize = file.Length;

WebRequest req = WebRequest.Crea te(url);
req.Method = "POST";

//Headers
req.ContentType = "multipart/form-data";
req.ContentLeng th = fileSize;
req.Headers.Add ("Name",file.Na me);
req.Headers.Add ("Path", path);
req.Headers.Add ("SessionID" , session);

Stream stream = req.GetRequestS tream();

using (BinaryWriter writer = new BinaryWriter(st ream))
{
FileStream fs = new FileStream(file .FullName,
FileMode.Open);

using (BinaryReader reader = new BinaryReader(fs ))
{
int i = 0;
long total = 0;

byte[] buffer = new byte[32768];

while (((i = reader.Read(buf fer,
0,buffer.Length )) 0) && !Stop)
{
writer.Write(bu ffer,0,i);
total += i;
uploadWorker.Re portProgress((i nt)(total *
100 / fileSize));
}
}
}

req.GetResponse ().Close() did the work. Thank you.

If the server is working at all, there is always a response for each
request. Even an error message (for example http 404) is a response.
