Enable HTTP Compression of Dynamic Content (IIS 7)
Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista
Configure HTTP compression of dynamic content to use bandwidth more efficiently. Enabling dynamic compression always gives you more efficient use of bandwidth, but if your server's processor utilization is already very high, the CPU load imposed by dynamic compression might make your site perform more slowly.
Prerequisites
For information about the levels at which you can perform this procedure, and the modules, handlers, and permissions that are required to perform this procedure, see HTTP Compression Feature Requirements (IIS 7).
