This works only with apache1.
apache2 and apache1 should support
my $href = $apr->headers_in;
here is a example:
Maybe you did not see the header, since the client must not send the referer
header.
#### Modelcode ######
# show all headers
sub alex {
my $model = shift;
my $href = $model->apr->headers_in;
$model->output(
headers => [ map { +{ name => $_, value => $href->{$_} } } sort keys
%$href
] );
}
