Sorry for the confusing title, I'll explain:
I've got a vhost set up for sd.example.com. DocumentRoot is htdocs/sd. Browsing to sd.example.com works as expected. But if I browse to sd.example.com/sd, I get the same result.
Is this expected behavior, and if so, how to disable it? I would have thought sd.example.com/sd would try to load htdocs/sd/sd, which should result in 404.
Happy to post my vhost confs if it isn't expected.
