HTTP compression is a long established web standard that is only now receiving the attention it deserves. Its implementation was sketched out in HTTP/1.0 (RFC 1945) and completely specified by 1999 in HTTP/1.1 (RFC 2616 covers accept-encoding and content-encoding). Case studies conducted as early as 1997 by the WC3 proved the ability of compression to significantly reduce bandwidth usage and to improve web performance (see their dial-up and LAN compression studies).

On Microsoft IIS 4.0 and 5.0 web servers, httpZip is the best solution for compression as it addresses a number of shortcomings in functionality, customization, and reporting on Windows NT/2000 that gave rise to a third party tools market.
With the launch of Windows Server 2003 and IIS 6.0, Microsoft chose to make compression functionality a priority, and their internal IIS 6.0 compression software works - though you must delve into the IIS metabase to manage it beyond a simple on/off decision. You can use a tool like ZipEnable to unlock and greatly enhance the configuration and management options for IIS 6.0 built in compression.
