in thread mod-perl2 re-using $ENV{REMOTE_ADDR}

I would write that: 
@IPs=split /,/, $ENV{HTTP_X_FORWARDED_FOR} // $ENV{REMOTE_ADDR};

as it is both shorter and clearer in its intent, and doesn't pointlessly set @IPs only to immediately re-set it. For pre-5.10 you'd have to use a conditional operator, which is left as an exercise for the reader.
