INTRODUCTION
This article clarifies the terminology that is used to describe the amount of memory that Microsoft Internet Security and Acceleration (ISA) Server 2004 uses for caching.



MORE INFORMATION
When you click the Advanced tab of the Cache Settings dialog box in the ISA Server Management utility, the following option appears:

Percentage of free memory to use for caching

This option seems to indicate the amount of available memory that ISA Server 2004 uses for caching. However, this option actually indicates the amount of physical memory that ISA Server 2004 uses for caching. A better or a more descriptive name for this option might be Percentage of physical memory to use for caching. This memory is allocated during the startup of the Microsoft Firewall service. Changes to this setting only take effect when you restart the Microsoft Firewall service.

To view the options that are on the Advanced tab of the Cache Settings dialog box, follow these steps:
 * 1) Start the ISA Server Management tool.
 * 2) Expand  , where   is the name of your ISA Server computer.
 * 3) Expand Configuration, click Cache, click the Tasks tab, and then click Configure Cache Settings.
 * 4) Click the Advanced tab.
