Configure the Maximum Cache Size Limit (IIS 7)
Applies To: Windows 7, Windows Server 2008, Windows Server 2008 R2, Windows Vista
Set the maximum output cache size when you want to limit the amount of memory IIS uses for output caching. Maximum cache size is the maximum size, in megabytes, of the output cache. When the default value of 0 is set, IIS automatically manages the cache memory size.
|Setting a value that is too high could lead to the output cache using too much memory and may aversely affect performance of the server and application components. Exercise caution when you configure this value.|
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 Output Caching Feature Requirements (IIS 7).

In Features View, double-click Output Caching.
On the Output Caching page, in the Actions pane, click Edit feature settings.
In the Edit Output Cache Settings dialog box, enter the maximum cache size, in megabytes, in the Cache size limit (in MB) box.

|When you use Appcmd.exe to configure the <element_name> element at the global level in IIS 7, you must specify /commit:WEBROOT in the command so that configuration changes are made to the root Web.config file instead of ApplicationHost.config.|
