UNIX Web Server Search

A WWW (or HTTP) server is a daemon program constantly running on an Internet-attached computer that responds to an incoming TCP connection and provides a service to the caller. The vast majority of WWW servers (about 72 percent) run on UNIX platforms around the world. And as everyone knows, flavors of UNIX outnumber flavors of ice cream at Baskin-Robbins. Consequently, you also can find many different kinds of WWW servers on those UNIX platforms.

Big surprise -- free servers are the most popular, with over 80 percent of the servers being free or proprietary. Most of these run on UNIX, but not all do. About 40 percent of the world’s Web sites use the NCSA HTTPD, with the CERN server is the second most used at about 12 percent, and Apache is third with about 7 percent. Several commercial servers are rapidly gaining popularity, due primarily to their ease of use and support for secure transactions. The major commercial player in the UNIX market is Netscape with about 6 percent of the sites worldwide.
