Dear Francois,
Many thanks for taking the trouble to reply. I will do as you suggest.
I've used the Web App Debugger tool in Delphi, but this shows me little more
than I can see in your error messages (which I can also see by setting
breakpoints in your programming and examining the values of variables).
May I say that I've used your ICS components - particularly the SMTP
component - since Delphi 1 or 2 days (if you keep a record, you'll find me
with a Stellenbosch address and e-mail address [EMAIL PROTECTED]), and
this component has sat working without complaint in the software I make and
maintain for the company I work for. I started using your SMTP component
because my brother had started a company and I helped him by making software
for him (his company) in my spare time. The company obtains visas (yet
another WeQ4U company). My software started out as a means of tracking a
visa application, but it took over my life so much, that I decided to leave
my job in the University and come to work for my brother. The program using
your SMTP component has grown to a complete business software tool - e.g. it
has a salary sub-system, it reconciles a bank statement, etc., etc.
Communicating with our clients - travel agents - is important to us. We
send out circulars saying something like The French embassy now wants two
colour photographs, black-and-white is no longer acceptable. These go out
through you component. We also send e-mails saying something like We
lodged your application for a multiple-entry visa to China today and these
also go out through your SMTP component. These e-mails are constructed from
information in the database underlying the software. Your component allows
the software to pump out about 1000 e-mails per work day. That this all
happens without human intervention astonishes me. I was born in 1947 and
remember the technology of the time - like the surplus military 3-ton truck
my father owned. The gears crashed and the differential whined!
Another component of yours I use is the HTTPCli component. I made a
program, called Screen2Screen, which travel agents install on their PC's.
It delivers the costs and requirements for visas, along with an application
form and it manages the progress report e-mails we send out. The HTTPCli
component is embedded on this program. There must be about 600 active
copies of the program running on PC's all aver South Africa. So you can say
that you play a part in the daily life of people in the travel industry of
South Africa! Our portal's URL is www.visas.co.za.
In short, many thanks for your contributions!
John Randall.

Is anybody willing to
give me advice on how to squash this bug?
Use a network sniffer to spy on the LAN cable and see if the request is
what you expect it to be, what the CGI expect it to be, see the difference
between your two clients.
You can use Ethereal which is free. Link is on my links page at my
website.

Subject: [twsocket] Unhelpful error message from the HTTPCli
This query relates to the HTTPCli component.
I have a web client and server pair which is not co-operating and I can't
find the bug. Lets call this pair A. I have another pair, call it B,
which is working just fine - and has been for a while. If I change the
string (content) sent and the URL, to the values for B, client A
works just fine, so the problem must be with server A. Either its the
program, the string sent, or the URL.
The bug gets more frustrating. Server A is in folder A on the server PC
and server B in folder B. Copying server A to folder B and modifing the
URL appropriately, I tried client A again. There's still an error, but a
different one!
I don't believe the errors to be relevant (I think they're misleading)
but when I use client A to send to server A in folder A, I get the
Method not allowed error. When I send to the copy of the server in
folder B, I get File or network error.
I'm using the POST method and the server is a CGI script. I'm
programming in Delphi 7 on an XP PC and the server is a Windows 2000 PC.
My belief is that the problem is the server program. Is anybody willing
to
give me advice on how to squash this bug? I hope the above is sufficient
information, but I'd be delighted to supply any missing detail. I
appreciate that
the HTTPCli component is working just fine, but the error messages it's
giving
me aren't leading me to the cause of the problem.
