It is doing exactly what you told it to do. You need a '../' for each
path part after
app.cgi.

The best method is to use an absolute path like you suggested:

# code not tested
my $home_url = $cap->query->url( -absolute => 1 ) . '/home' );
$cap->redirect( $home_url );

or if you absolutely must use a 'relative' url:

my @levels = split /\//, $cap->query->path_info;

my $home_url =  $cap->query->url(-absolute => 1) . '../' x @levels . 'home';
$cap->redirect( $home_url );

I'd still go with option one (absolute url)
