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 
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
