WebRequest - large files - timeout problem.

[Piotrekk]

Hi

I am trying to upload a 700 mb file using webrequest/response model.
At 3x% I am getting the same error:

"Unable to write data to the transport connection: an established
connection was aborted by the software in your host machine"

CLIENT side script is:

req = WebRequest.Create(
req.Method = "POST";

//Headers
req.ContentType = "multipart/form-data";
req.ContentLength = fileSize;
req.Headers.Add("Name", file.Name);
req.Headers.Add("Path", path);
req.Headers.Add("SessionID", session);
req.Timeout = int.MaxValue;

Stream stream = req.GetRequestStream();

using (BinaryWriter writer = new BinaryWriter(stream))
{
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(buffer, 0,
buffer.Length)) > 0) && !Stop)
{
writer.Write(buffer, 0, i);
total += i;
uploadWorker.ReportProgress((int)(total *
100 / fileSize));
}
}
}





SERVER side script is:

Stream inputStream = HttpContext.Current.Request.InputStream;

using (BinaryReader reader = new
BinaryReader(inputStream))
{
FileStream fs = new FileStream(fullfile,
FileMode.Create);

using (BinaryWriter writer = new
BinaryWriter(fs))
{
int i = 0;
byte[] buffer = new byte[32768];

while ((i = reader.Read(buffer, 0,
buffer.Length)) > 0)
{
writer.Write(buffer, 0, i);
}
}
}

Server has <httpRuntime maxRequestLength="102400" /> in its config
file.

Would be grateful for help.
Kind Regards
PK

Increase that value. It represents the maximum data amount that can be
uploaded in kB. Your maximum therefore is 100MB which doesn't quite
cover your 700mb

Cheers,

I think you should find another way to upload such a big file, IIRC
the maximum size for ASPNET is like 100MB
