"Program Working" web page ?

[still just me]

What is/are the technical approach(s) used to display "program
working" web pages?

I understand the cgi cycle well... and I'm thinking that if I send a
response page to the user with "program working" that then I'm all
done - I can't send another page of output with the program results.

I have a program that sometimes takes a little bit of time to run and
unless the used watches the browser indicators, I'm concerned that
they will terminate it early (before the results are sent to them).
I can think of some ways to do this with Javascript in the client, but
are there techniques to do this with cgi headers that are server
driven?

Thanks,

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.

Well, because many of the folks here who write Perl are well versed in
using Perl for CGI applications and I know that some of them likely
have the expertise to answer the question. In addition, there are no
active groups that I know of that are dedicated to a discussion of CGI
programming at this detailed level without being bound to some
specific programming language.

Jürgen, your fanatic resistance to anything CGI is tiresome!

there are no active groups that I know of that are dedicated to a
discussion of CGI programming at this detailed level without being
bound to some specific programming language.

But this list might be worth trying:

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.

Thanks Gunnar, looks promising...

How about using <meta http-equiv="refresh" content="30">
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.

I understand the cgi cycle well... and I'm thinking that if I send a
response page to the user with "program working" that then I'm all
done - I can't send another page of output with the program results.

I have a program that sometimes takes a little bit of time to run and
