Web Service Cache Object

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

The Web Service Cache object counters installed with Internet Information Services monitor file transfer rates, bandwidth usage, and connection rates.

You can view performance data for all instances of this object (using the _Total instance) or for specific instances, such as the Default Web Site or Administration Web Site instances.

In addition to these counters, counters supplied by the Internet Information Services Global performance object combine data for the Web service with the performance data they report for IIS as a whole. For more information, see the Internet Information Services Global Object.
