Actually I am. Check out MainHandler() which is the content handler. The $response->content() will return to the web client the data specified. In this case, I'm calling the sub get_content().

sub MainHandler {
    my ($request, $response) = @_;

    $response->code(RC_OK);
    $response->content( get_content($request) );

    return RC_OK;
}

The handler is declared in create_httpd() which I didn't include in the OP :

sub create_httpd {
    my ($kernel, $heap, $Port) = @_[KERNEL, HEAP, ARG0];

    $kernel->alias_set('httpd_parent');

    my $httpd = POE::Component::Server::HTTP->new (
        Port => $Port, ContentHandler => { '/' => \&MainHandler } );

    $heap->{httpd} = $httpd;
}
