Exactly the same as you would use if your program were written in C,
Pascal, VB, or any other programming language.

Why don't you ask in a NG that is actually dedicated to discussing web
programming instead of in a NG that is about the Perl programming
language.

Jürgen, your fanatic resistance to anything CGI is tiresome!

But this list might be worth trying:

My solution is to send some characters to visitor's browser and some
"needless" spaces to overfill browser's buffer.

print "program working, please wait ";
foreach my $cycle (1..10)
{
print ".", ' 'x512;
sleep 2;
}
print "
Done";

Maybe this help you.

I can accept "some", but "many" is a bit strong. I know *many* people who
have *never* written a CGI app in Perl, and yet are quite versed in Perl.
Heck, I was even in that camp for the first half dozen years of my Perl
experience.

This is also incorrect. CIWAC (comp.infosystems.www.authoring.cgi) certainly
covers this. I haven't poked my head in there lately, but it's definitely a
CGI group that is language agnostic.

s/covers/covered/

That group has been defunct for 15 months, so your mentioning of ciwac
won't likely make a difference.

I thought you were aware of it, btw.

Ahh, oh, yeah, ok. Hmm. I thought that it had started up again. Darn.

How about using
on the result page? Generate the result page at start of the program
with a "program running" message and regenerate the page with the actual
results later.
