You're bending the truth here, quite a bit actually. The HTTP 1.0 proto
may not support the Host: header, but browsers that are using HTTP 1.0
may very well support he Host: header. Oh, i don't know, a smallish
browser called Netscape, v 2.0 or better, comes to mind. Grepping
through my access log for today I see over 65,000 1.0 requests. 98% of
those are to name-based virtual hosts (which is almost all i run
anymore), and they all worked.
