off-host redirect

A homepage that answers with a redirect to a hostname outside its own www/apex pair, such as a regional storefront or a checkout host. The scanner does not follow it: whatever a crawler reads on the other host is attributed to that host, and the requested domain reads as a site with no homepage. Reported as HOMEPAGE_REDIRECTS_OFF_HOST.
