IMHO there is a bug in the docs: http://perl.apache.org/docs/2.0/api/Apache2/Connection.html#C_get_remote_host_
$remote_host = $c->remote_host(); $remote_host = $c->remote_host($type); $remote_host = $c->remote_host($type, $dir_config); It should be get_remote_host() instead of remote_host() ! Another aspect is not clear, when the 2 parameter form is used, how is the type of lookup determined? From $type or from $dir_config? Is $type to be set to undefined to make $dir_config relevant?
