The latest Netcraft web server survey finds only 21% of .com domains are using MS server software. I wonder why?
Netcraft shows Apache at 67%. Apache can run on just about any OS: Mac X/Linux/Unix, Novell Netware, Microsoft Windows, and some EBCDIC machines. Just because they're not running MS IIS doesn't mean they're Macs.
I didn't say they were on Macs, I was merely pointing out the rapidly declining population of Wintel boxes out there serving http.
In my experience, most production Apache installs are for Linux or other 'nix variants, with Windows very low on the list.
