HISTORY OF IIS
IIS was initially released as an additional set of Internet based services for Windows NT 3.51. IIS 2.0 followed adding support for the Windows NT 4.0 operating system and IIS 3.0 introduced the Active Server Pages dynamic scripting environment.
IIS 4.0 dropped support for the
Gopher protocol and was bundled with Windows NT as a separate "Option Pack" CD-ROM.
The current shipping version of IIS is 7.0 for
Windows Vista, 6.0 for Windows Server 2003 and IIS 5.1 for Windows XP Professional. Windows XP has a restricted version of IIS 5.1 that supports only 10 simultaneous connections and a single web site.[2] IIS 6.0 added support for IPv6. A FastCGI module is also available for IIS5.1, IIS6[3] and IIS7.[4]
Windows Vista does not install IIS 7.0 by default, but it can be selected among the list of optionally installed components. IIS 7.0 on Vista does not limit the number of connections allowed but restricts performance based on active concurrent requests
