IIS 6.0 offers support for the latest Web standards, including HTTP 1.1, TCP/IP, FTP, SMTP, NNTP, and PICS ratings.
IIS 6.0 complies with the HTTP 1.1 standard, which includes features such as PUT and DELETE, the ability to customize HTTP error messages, and support for custom HTTP headers.
Multiple Sites, One IP Address
With support for host headers, you can host multiple web sites on a single server running a member of the Windows Server 2003 family with only one IP address. This is useful for Internet service providers and corporate intranets hosting multiple sites.
IIS Extensions to FTP — New
IIS extends FTP in two significant areas. The IIS FTP User Isolation feature allows you to contain users to their own FTP directory, thus preventing them from viewing or overwriting other users' Web content. In addition, IIS supports multiple character sets for FTP, which allows your users access to their native-language worldwide.
UTF-8 Support — New
Support for Unicode and UTF-8 now extends to file names and URLs. Active Server Pages (ASP) can open any file name using the Unicode file name string. UTF-8 URLs are converted to a Unicode representation and presented to ASP.
Web Distributed Authoring and Versioning
Web Distributed Authoring and Versioning (WebDAV) enables remote authors to create, move, or delete files, file properties, directories, and directory properties on your server over an HTTP connection.
News and Mail
You can apply Platform for Internet Content Selection (PICS) ratings to sites that contain content for mature audiences.
FTP Restart enables File Transfer Protocol (FTP) file downloads to be resumed without having to download the entire file again if an interruption occurs during data transfer.
HTTP Compression provides faster transmission of pages between the Web server and compression-enabled clients. It compresses and caches static files, and performs on-demand compression of dynamically generated files.
