sockets and http question

[Guest]

im having a small bug now where if i give a http header GET / with a
connection: keep-alive i cant tell when the server is done sending. If i say
connection: close i dont have a problem. Here is breifly my code.

remember this works fine if i say Connection: close in the http header, if i
say keepalive it does not. anyone know why?

asynch send
------------------------
client.BeginSend(byteData, 0, byteData.Length, 0, new
AsyncCallback(SendCallback), client);


receive event
--------------
int bytesRead = client.EndReceive(ar);
if (bytesRead > 0)
{
//more packets
state.sb.Append(Encoding.ASCII.GetString(state.buffer,0,bytesRead));
client.BeginReceive(state.buffer,0,StateObject.BufferSize,0, new
AsyncCallback(ReceiveCallback), state);
}
else
{
if (state.sb.Length > 1)
{ //its done
response = state.sb.ToString();
receiveDone.Set();
}
}

Question: Why are you using TcpClient instead of WebRequest? This means
you must also implement all low-level TCP connection handling
faithfully according to the HTTP spec, which might be the problem here.

Ah, guessed wrong ;-)

The question remains, though -- why?

OK, now I do remember that thread ;-)

But what about the code I posted? No good?

That this doesn't answer anything. And that this is only shows the
complexity of what you need to deal with if you try this stuff at
socket level.
