Confusion over Apache2::Request and Apache2::RequestRec

[Douglas Sims]

I'm confused about something and I wonder if anyone can help me to
understand what's going on.  The code shown below works fine but as I was
looking over this before changing something else I realized that it probably
shouldn't.  I'm using an Apache2::Request object to return a connection
object to get the remote_ip but the documentation for Apache2::Request
doesn't show a connection method - that's in Apache2::RequestRec.

Why does connection() work on an Apache2::Request object?

Thanks!

Apache2::Request:
http://httpd.apache.org/apreq/docs/libapreq2/group__apreq__xs__request.html
Apache2::RequestRec:
http://perl.apache.org/docs/2.0/api/Apache2/RequestRec.html#C_connection_


In the PerlResponseHandler:

  my $requestrec = shift if $ENV{MOD_PERL};
  my $request = Apache2::Request->new($requestrec);
  my $session = Sessions->new($request, $mysql);



{package Sessions;

  sub new {
    my $class=shift;
    my $self={};
    bless ($self, $class);

    $self->{REQUEST}=shift;
    $self->{DBH}=shift;

{...snip...}

        $self->{DBH}->do('INSERT INTO failedloginattempts (username,
password, ip, session, attempttime) VALUES
('.$self->{DBH}->quote($username).','.$self->{DBH}->quote($password).',
INET_ATON('.$self->{DBH}->quote(*$self->{REQUEST}->connection()->remote_ip*).'),
'.$self->{DBH}->quote($self->{SESSION}).', NOW())');
