This section describes web servers , programs whose main purpose is to serve up HTML pages. programs described in other groups also can perform as http servers. for example the Java containers and application servers often has a built in HTTP server.
On the surface, web servers selection is quite simple about 60% of the worlds web servers (depending on how you count) runs on Apache and most of the rest run on Microsoft IIS. Turns out that the rest is quite an interesting collection.
A significant part of them are lightweight httpd servers like lighthttpd or nginx built for limited purposes like serving static httpd pages. Another group is bulit for special environments like Ruby or the Symbian operating system.
