$is_admin_link isn't in your list so it being defined doesn't matter. The second part of my node addresses most of your example while the first part of my node addresses the $is_admin_link part:

my $uri = join '/', grep defined $_, 'http://ex­ample.net/­app', ( grep $is_admin_link, 'admin' ), $subsite, $mode, $id, $submode;
