I think you should read from instream and write to outstream.
Maybe that's the problem (I am not sure, as I don't have the full source).

Stream instream = response.GetResponseStream();
Stream outstream = context.Response.OutputStream;

int outcount = instream.Read(buffer, 0, buffer.Length);
while (outcount > 0)
{
    outstream.Write(buffer, 0, outcount);
    outcount = instream.Read(buffer, 0, buffer.Length);
}
// Close streams
instream.Close();
outstream.Close();

Also, I think the best pattern is:
Create a TcpListener.
Start it.
In a loop, you accept a TcpClient, start a thread to process the client and continues in the loop accepting new requests.

TcpListener listener = new TcpListener(IPAddress.Any, m_port);
listener.Start();

while (true)
{
    Socket client = listener.AcceptSocket();
    ThreadPool.QueueUserWorkItem(ProcessSocket, client);
}

And, finally, maybe the connection is lost in the middle. This can happen (think about the stop button, for example). So, if the connection is closed, it's ok. Ignore this exception.
