To expound, the two URLs refer to different hosts.

The first URL refers to a resource "/projects/kobjects/" within the
"" host, the second to a resource "/" within the
"" host.

It is possible for DNS to resolve both hosts to the same IP, and for
the web server there to resolve both resources to the same directory.
There's no way for the user at the browser to know for sure. Even if
both URLs do resolve to the same directory, the permissions and
accessibility within the resource could differ. Proxies and reverse
proxies complicate matters further.

such games. It's a marvelous product.
