Know About IIS 7.0

Introduction
Internet Information Services is a set of Internet-based services for servers using Microsoft Windows. It is one of the most popular webserver in the world.
Prior to IIS 7.0 there are already 6 version of IIS released, the last version of IIS is IIS 6.0 which runs on Windows XP Professional x 64 edition and Windows server 2003 which is a restricted version that supports a limited number of connections and a single web site.
IIS 7.0 is designed for Windows Vista clients , the local IIS 7.0 web server will change not to limit on connections but will limit workloads based on the active concurrent requests improving usability and peer-to-peer scenarios
IIS 7.0 1
Debuting with Windows Vista and also to be included in Windows server LongHorn, IIS 7.0 will feature a modular architecture. Instead of a monolithic server which features all services, IIS 7 will have a core web server engine. Modules offering specific functionality can be added to the engine to enable its features. The advantage of having this architecture is that only the features required can be enabled and that the functionalities can be extended by using custom modules.
The following sets of modules are slated to ship with the server:
1. HTTP Modules
2. Security Modules
3. Content Modules
4. Compression Modules
5. Caching Modules
6. Logging and Diagnostics Modules
Writing extensions to IIS 7 using ISAPI has been deprecated in favour of the module API. Much of IIS's own functionality is built on this API, and as such, developers will have much more control over a request process than was possible in prior versions. Modules can also be written using any >Net Framework language, and can be deployed on a per-site basis.
A significant change from previous versions of IIS is that all web server configuration information is stored solely in XML configuration files, instead of in the metabase. The server has a global configuration file that provides defaults, and each virtual web's document root (and any subdirectory thereof) may contain a web.config containing settings that augment or override the defaults. Changes to these files take effect immediately. This marks a significant departure from previous versions whereby web interfaces, or machine administrator access, was required to change simple settings such as default document, active modules and security/authentication. It also eliminates the need to perform metabase synchronization between multiple servers in a farm of web servers.
IIS 7 also features a completely rewritten administration interface that takes advantage of modern MMC features such as task panes and asynchronous operation. Configuration of ASP.NET is more fully integrated into the administrative interface.
Other Changes
1. PICS content ratings, support for Microsoft Passport, and server-side image maps are no longer included.
2. Executing commands via server-side includes is no longer permitted.
.
3 IISRESET -reboot has been removed.
4 The CONVLOG tool, which converts IIS log files into NCSA format, has been removed.
5 Support for enabling a folder for "Web Sharing" via the Windows Explorer interface has been removed.
