Thanks for your reply.If I try something like 

#!/usr/bin/perl

use Data::Dumper;
print "Content-type: text/plain\n\n";
print Dumper \%ENV;

as test.cgi to run in apache the env vars heavily differ from everthing seen at login shell
(i know 
that apache runs in a special environment most of time) or, even more strange, from the environment

variables the apache process knows about. (seen in /proc/PID/environ)

I simply can not adopt my applications to re-write the %ENV - I really need apache to do that

initially for all cgi scripts.
