A HEAD request to
<http://arielpartners.com/arielpartners/content/public/home/resolver?nid=arielpartners&nss=topics/offerings/products/conflux>
results in a 404 Not Found, see the attached dump from a request done by
my local copy of checklink.  The other two are similar cases.

Additionally, if the request is a GET without the "Host" HTTP header,
the URL above returns a redirect to a resource on a host named
vivaldi.arielpartners.com, which doesn't resolve.  If it's a HEAD
without a Host header, the resulting error page also contains a <base
href=...> also containing vivaldi.arielpartners.com.

"Modern browsers" usually do a GET with the Host header, that's why
they're not affected.
