Use the Edit Output Cache Settings dialog box to configure settings that affect the entire Output Caching feature. These settings affect all the output caching rules that you configure on the Output Caching feature page.
UI Element List
Enables the IIS output cache, which stores cached responses in user mode.
Enable kernel cache
Enables the kernel cache, which stores cached responses in kernel mode. Performance is improved when responses are returned from the kernel cache without transitioning to user mode.
Maximum cached response size (in bytes)
Specifies the maximum size of a cached response for both the user-mode and kernel-mode caches. The default value is 262144 bytes. This field is enabled at the server level only; it is read-only at all other levels.
Cache size limit (in MB)
Configures the size limit of both the user-mode and kernel-mode caches. You can type a size (in MB) or type 0. If you type 0, IIS uses half of the available physical memory or virtual memory, whichever is less. This field is enabled at the server level only; it is read-only at all other levels.
