That it does.

Visiting http://example.com/index.html.nyud.net would send a request to "example.com" for the path "/index.html.nyud.net". That's not what you want.

Thanks for pointing this out, I had really never noticed that before. I feel slightly silly now -- obviously the nyud.net was just being passed as in the query string...

Yup!
