dns problem with browsers only?

It's just a crappy webserver that unceremoniously closes the HTTP connection
whenever it doesn't recognize the Host: header on an HTTP request. Your
resolver, presumably with the help of a default domain or a searchlist, helped
you get *to* the webserver, but then, because of the name you used to access
it, the webserver's user-unfriendliness prevented it from sending you back
anything meaningful, not even a proper error response. This behavior probably
violates the HTTP RFC (but I'm too lazy to look that up right now).
Have I seen this *particular* bogosity before? Not that I can recall. Have
I *generally* seen shoddy behavior like this from mainframe-based web
servers? You betcha.
