Hello Wilfried,
Sure. Below is my event handler code. Hope I'm doing something
wrong, otherwise, it's really strange. TProxyChecker is the owner
object of the TProxySocket object array. TProxySocket is derived
from TWSocket.
procedure TProxyChecker.WSocketDataAvailable(Sender: TObject; ErrCode: Word);
var s: String;
begin
if ErrCode = 0 then
with TProxySocket(Sender) do
begin
s := ReceiveStr();
Log(s);
Close();
end;
end;
The destination server is a commercial http proxy server.
I tried using #13#10 and #13#10#13#10, I different strings
read back from ReceiveStr. But the second string includes
the first string in both cases. So it shouldn't be the server
sending the string twice.
BTW, I'm using the latest ICS.

Jack
