The web server market is divided into two areas- intranet servers and public web servers. Some servers run on only one operating system and some others run on several operating systems. The four most popular web servers are listed below. Netcraft frequently conducts surveys to determine the number of websites for measuring the relative popularity The performance of one web server will be different from another based on workload, operating system, size and type of programs. The commonly used web servers are a)Apache http servers It dominates the web in numbers, in part because it is free and performs very efficiently and it is powerful too.

It can be managed either from server console or from a browser. Wizards are available to create new sites and directories. It offers high security with password and digital certificate authentication. Apache supports CGI and APIs. It also supports Server Side Includes (SSI). It also supports ASPs and Java Servlets. It supports ODBC standards and can access Oracle, SQL server etc. b)Microsoft Internet Information Server(MIIS) It comes with Windows NT OS. It is the second most installed web server software.

NES provides local publishing mechanism. NES also provides document conversion, indexing utility programs and search engines. NES management tool allows administrator to manage users and monitor server activity. It provides cluster management so that administrator can manage multiple servers. NES provides password, user authentication and digital certificate. Netscape Directory server (NDS) provides basic security mechanisms. NES provides dynamic application development with CGI and API. NES includes a runtime enviroment called Livewire. NES also Supports a variety of databases- oracle, Sybase, Informix etc 4)O’REILLY’S Website professional It supports Win 95/98 and Win NT.
