I recently read the tcp/udp primer under the overbyte.be support section
and the tcp data fragmented packet example using the text string Hello
caught my attention because that is something i always wondered about in
socket programs. The fact that the data can be split up into multiple
packets
Unless you are using UDP and instead using TCP, you do not need to worry
about fragmentation: MS TCP layer would handle it and Winsock will just fill
your buffer--the size you want. There is one exception: the last packet. You
should check for connection termination and packet sizes of smaller
strictly through the protocol implementation) how can I force WSocket's
OnDataAvailable event to queue the data until it's assembled into one
large
chunk so i can then process it as if it all arrived that way instead of
split up.
TWSocket will do that for you in the case where your chunks

I have to use ICS to send some images to another computer over the network .
now I have to ask how can I send stream using wSocket from a side and how can I

You have to better define what you mean by stream.
For example, I don't know if you think about a TStream component or some
kind of audio or video streaming.
Define your requirement a little bit more if you want to be helped. In

Hi
What happens when THTTPCLI.close procedure is called? Does it always
call OnRequestDone event?

connection timeout and verification timeout. So i made something

Why don't you use onsessionclosed. Not sure but it should work for your
close problem. OnRequestdone should also be called for me.

Only one timer is enough for all your timeouts.
You could implement this way:
You timer would trigger each 10 seconds (or any other interval you like).
Your timer event handler will check a list of timeout actions. Each timeout
action could be a time value to check against current time and an

Why not use a timer and launch the second request on OnTimer? You would need

You never wait with ICS since it is asynchronous.
You can implement retries using a

With ICS, you don't need to use multithreading to have 20 HTTP components
running in parrallel doing different things ! Use multithreading for your
blocking processing, if any. It will be much easier to develop and debug.

I noticed that if I'm not doing anything with RCVStream of HTTPCli
in requests im getting Stream with data from previous requests that
were made on the component. How do i avoid it? How to cleanup

Try RcvStream.Position := 0; when resetting ...
If you set it to nil, it is obvious you'll get Access Violations.

Again, you don't need multithreading for your few 20 THttpCli instances.
ICS can easily handle more instances (faster) in a single thread and it is
much easier to code.
