This does not belong on nanog, but to set the facts straight: if Netscape
Enterprise 2.0 supports Host: based virtual hosts but only for hosts that
make HTTP/1.1 requests that is lame. Versions of Navigator have sent
Host: headers for some time; so has MSIE. Last I knew, AOL's proxies
didn't yet because they were too lazy. The vast majority of clients do
send Host: headers even though they aren't HTTP/1.1. HTTP/1.1 clients
_have_ to send the Host: header, but HTTP/1.0 clients may and most do.
I do not advocate using them yet for most websites, but that is another
