how to set env variables?

Hi,
I have a perl script that runs just fine from command line but not when
I run it as cgi. I think it's because there are some env variables that
doesn't exist when I run it as cgi. Is there a way to set the variables
from the perl script?
I tried $ENV{'VAR'} = 'value';
but it doesn't make a difference.
btw, I'm using apache as the webserver. Should I set the env variables
from apache config instead?
any suggestion?

thanks,
- reynard

That usually works.

Perhaps it's not an environment variable problem.

That will set the variable across the entire server
and is one recommended way. What happened when you tried
that?

Show us your code. Let us confirm your reasoning.

Did you try, restarting the apache server. As some thread/processes might
still carry the old values

I think I figured it out now, I set it from the httpd.conf like this
SetEnv VAR "Value"
and restart the apache, now it works.

thank you all for the suggestions,
