Hi monks, I have a CGI script which is called with a trailing path:
http://www.example.com/script.pl/foo/bar
To get the individual elements of the path I use a subroutine 
sub get_paths_from_url {
  my $path = $ENV{'PATH_INFO'};
  return if not $path;
  $path =~ s|^/||;
  $path =~ s|/$||;
  my @paths = split('/',$path);
  return \@paths;
}

I'm a bit wary of this as I'm sure I've read that parsing anything from the web is error prone. My question is - is there anything inherently dangerous about this approach, and should I just use a module?
