Apache is a freely available Web server that is distributed

under an "open source" license. Version 2.0 runs on most

Unix-based operating systems (such as Linux, Solaris,

Digital UNIX, and AIX), on other UNIX/POSIX-derived systems

(such as Rhapsody, BeOS, and BS2000/OSD), on AmigaOS, and on

Windows 2000. According to the Netcraft (www.netcraft.com)

Web server survey in February, 2001, 60% of all Web sites on

the Internet are using Apache (62% including Apache

derivatives), making Apache more widely used than all other

Web servers combined.
