Hello,
I noticed that the HttpCli component return the 404 status code not
only when the server return this code but even under different
situations. For example when it is unable to resolve the hostname or
when wsocket raise an error (please correct me if I'm wrong).
This is a problem because th

One can still use gettickcount then. One only has to combine it with your

Not if she use GetTickCount which returns the nb of milliseconds since the
system is up and running. Restart to zero after approximately 49 days. That
is perfectly suitable for timeout determination.

Hello Arno,

No it is not OT, it is interesting since timeouts are often handled in
comm programs. I have no Delphi open, but I have some programs where I
have separate class to get me elap seconds, minutes etc. Something like
this (whitch will rollover after 136 years, so ple

Never use TDateTime to measure time durations in Delphi, instead use
GetTickCount which returns milliseconds since Windows booted as a
simple longword.

Sorry for being OT, but that's why I suggested a tiny little
helper function also for use in ICS, something like:

From the top of my head:

DateTime returns the day's elapsed since 30 dec 1899. eg: 2 is 1 jan
1900 00:00, 1.5 is 1 jan 1900 12:00 etc. Meaning the fractions ar jsut

Maybe you are referring to the first use I made of MsgWaitForMultpleObjects.
Since then, I have changed the order in the code and now there is no more
slow down, imo.

HttpAsy is a simple application which take a list of URL and either get
those URL one after the other (sequencially) or get all at the same time
using a component for each one.

Hello Ann,
Several scenario's are possible. Depending on what you exacly have to do
it is maybe interesting to make a separate class that manages the
connections. But the principle is always the same.
- you mention you need timeout, So you derive a component from THttpCli
and give it a timer.

Both MsgWaitForMultpleObjects and Sleep seriously slow down a program
that's
trying to do multiple jobs at the same time.
