Having read the last few breads with only the bad cert being called, and the Q has referenced apache http multiple time, I thought some anon would understand the difference of the two links.
When a site is www.Army.mil, the DNS will resolve at army.mil, the main site. When you add a /inscom, the resolution still goes through army.mil. The second link, is structured differently. With www.inscom.army.mil, that doesn't resolve according to army.mil, it is part of a subdomain, and treated as a seperate directory. Someone may control army.mil, but inscom.army.mil would be anyone else, including certificates.
