Using HTTP Compression

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1

To more efficiently use available bandwidth, enable IIS HTTP compression. HTTP compression provides faster transmission time between compression-enabled browsers and IIS, regardless of whether your content is served from local storage or a UNC resource. You can compress static files and application response files. Compressing application response files is usually called dynamic compression.
