The "host" header became mandatory in HTTP 1.1

http://rfc.net/rfc2616.html#s14.23

It was optional in HTTP 1.0

http://rfc.net/rfc1945.html

Many HTTP 1.0 implementations chose to provide the "host" header anyway,
even though it wasn't mandatory, to facilitate virtual hosting. The most
notable of these is Netscape 4.x. 

I believe that there are very few browsers left out there that don't
supply the "host" header.
