Hi,
I would go to the javascript wrapper solution :
I would wrap cgi-script to send javascript code to browser and then
redirect original script output to the html file
In a javascript I would loop (and sleep) until load of html file will
succeed.

Thanks for the help! Based on it I tried running the command with
python as follows:
import subprocess
pipe = subprocess.Popen("do_slow_command 2>&1",
bufsize=1,
stdout=subprocess.PIPE,
stdin=subprocess.PIPE,
shell=True)
for p in pipe.stdout.readlines():
print p,"<br>\n"
According to the subprocess documentation, this is supposed to set up
line by line mode. But I still get things buffered up. But perhaps
that is because I did not tell "do_slow_command" to flush after print
command, and it senses that it is not being run under a terminal? I'll
try that.

I'm trying to write a cgi wrapper for a long running
command. The command takes about 10minutes to execute and
when running it from the command line it continously
outputs text to stdout. A simplistic cgi-bin wrapper that
tries to execute the script and then writes that it is
done fails with the following message:
Timeout waiting for output from CGI script ...
What I wonder if there is any easy way to have continously
update the web page with stdout of the script.
One way, I guess would be to run the script in a separate
thread and just do HTML reload on a static page which I
would regenaret with the stdout generated so far.
Is there any other simple solution?
You could increase the timeout to be > running time of the
script ...
Do not forget that you also have timeout of the web browser that
you can not control (you can not control the users themselves).
