Hi Arno Garrels, I looked over the code of "THttpCli" and if you do not have a connection from localhost to localhost it may work... I expect this in particular cause the read of Megabytes is done within split seconds, also if my program is sleeping (for example on a breakpoint in Delphi).
The problem is that the read occures within miliseconds because localhost does not have any latency. In the case of THttpCli ther there is a 1000ms timer: I think this is much too slow to prevent the reading of so many data (Megabytes!) within this small time, isn't it? In my Client ICS Proxy software I have my own Message Loop, I don't juse socket.MessageLoop but process the messages in .Execute of my Thread by myself. If the problem would be the messages, then I would be able to ignore them there... But the read is done if my Client sleeps (for example on a breakpoint) or not! So I think the messages are not the problem... Maybe it is a general Winsock problem about Async read? Is it possible to put a Socket into a Sync read? Thanks in advance for any hints... I am completely frustrated about this problem... I just wanted to implement Flowcontrol into my Application, which I have developed over a month... And now I must search for a completely new network framework and must begin from root? :-( Much regards, Markus Mueller > Markus Mueller wrote: > > >> it buffers sometime within 2-4 MByte before "socket.pause" does help, >> my >> >>> 3 Ghz Dualcore >>> >> seems to buffer also hunderts of MByte... >> > > procedure TCustomWSocket.Pause calls winsock API WSAAsyncSelect. > It simply tells winsock to stop posting notification messages. > > "Although WSAAsyncSelect immediately disables event message posting > for the socket in this instance, it is possible that messages could > be waiting in the application message queue.
