Exploring Web Server Options

Apache is not the only web server available; there are actually some proprietary web servers that you can buy. Table 30.1 briefly describes several of the important ones. According to the Netcraft survey, four web servers are currently run by more than one percent of the websites on the Internet: Apache, Microsoft s Internet Information Server, Zeus, and Sun Microsystems s Sun One.
