The procedure "IsAddressValid" in the ICS demo project "HttpChk" works
well to check the validity of a URL, but it is very laggy. If you want to
do checks on multiple websites it is much too lengthy/laggy. Is there a
better solution for checking the validity of a URL?

Is there a better method of doing this? If so, a small example would be
GREATLY appreciated.

for Item := 1 to CheckListBox1.Items.Count do begin
AHttpCli := THttpCli.Create(Self);
with AHttpCli do begin
MultiThreaded := True;
FHttpCliList.Add(AHttpCli);

So I should issue GetAsync and handle RcvdStream in the OnDocData event,
correct?

the default document name? Whether it be "index.html" or "main.html" or
just some custom name specified on the webserver?

I have tried to implement an exception handler for this event but was
unsuccessful. I have also read of similar complaints from other people. A

I have tried assigning a procedure to handle this exception using your
suggestions, using this code:
-
HttpCli.CtrlSocket.OnBgException := ExErr;
...
procedure TForm1.ExErr(sender: TObject; E: Exception; var CanClose:

Thank you for the response Francois. I've tried using a try..except

recommend handling these exception errors?

Why is ICS written to trigger an exception error upon events such as an
internal server error, or when a connection request is aborted in the
middle of receiving data from the server? The code I am referring to is
this:
if (FStatusCode >= 400) and (FStatusCode <> 401) and (FStatusCode <> 407)
then
