NetworkStream.W rite giving "forcibly closed" upon streaming

[Almund]

Hi,
I'm trying to implement streaming over http and got stuck with a problem trying to send chunks of data using the .Net NetworkStream object.

All works fine as long as I send the entire data in one invocation to the NetworkStream, like:

_stream.Write(buffer, 0, buffer.Length)
 

But if i try:

byte[] buffer = new byte[4196];
int bytesRead = Body.Read(buffer, 0, 4196);
while (bytesRead > 0)
{
    _stream.Write(buffer, 0, bytesRead);
    bytesRead = Body.Read(buffer, 0, 4196);
}
 

I get the following exception: (sorry for the mess)
HttpRequestPars er.ParseMessage => HttpClientConte xtImp.OnRequest Completed => HttpServer.Setu pRequest | Failed to respond on message with Internal Server Error: System.IO.IOExc eption: Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host. ---> System.Net.Sock ets.SocketExcep tion: An existing connection was forcibly closed by the remote host
at System.Net.Sock ets.Socket.Send (Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags)

--- End of inner exception stack trace ---
at System.Net.Sock ets.NetworkStre am.Write(Byte[] buffer, Int32 offset, Int32 size)


Only difference I can see is that the stream sends the data in bits (I do send some http headers in both case but i´ve stripped some of that code since its productioncode) . Another twist is that it works when sending the code to for example Firefox but when trying to stream it to ie embedded data in a webpage it breaks.

Any help would be greatly appreciated.

Did you send the "connection : keep-alive" header?
I'm not sure how streaming fits into the http protocol (I knwo it can be done, i've seen it) but the HTTP protocol specifies you give a content length, maybe there is something in that?
