Just out of curiosity, wouldn't it be better to test with exists()?
I did a quick test using env.pl, which confirms that for me as well, the
PATH_INFO variable exists only if there actually is something in the url.
That is:
http://foo/bar.pl -> no PATH_INFO exists in %ENV
http://foo/bar.pl/ -> PATH_INFO = /
This holds both under mod_perl (with ModPerl::Registry) and under mod_cgi. My
Apache is 2.0.52.
As an aside, I have distant memories of IIS/5.0 not being able to do path_info
at all, at least not without certain arcane rituals too gross to detail here.

#!/usr/bin/perl
# env.pl
print "Content-type: text/plain\n\n";
print map { "$_\t=$ENV{$_}\n" } sort keys %ENV;
# end

environment"; }
I wrote a tiny CGI script containing:
my($env_path_info) = defined($ENV{'PATH_INFO'}) ? "Defined:
$ENV{'PATH_INFO'}" :
"Not defined";
and that displays Not Defined. Again, this is Apache V 2.
So it seems your assumption that path_info is always defined, is wrong, at least
in the case of non-mod_perl handlers.
