That's not the only thing IIS does that's kinda silly. I remember
reading that (some version of) IE & IIS don't bother with all that
pesky protocol setup stuff, IE just fires off a packet asking for the
page it wants. Any other web server would go "huh? who are you?", so
IE backs off and does the protocol setup. IIS reacts by sending the
page back, thereby making it *look* like the IE/IIS combination is
nice and speedy.

Instant rigged demo. Good, eh?
