  configSection.EnableKernelOutputCache + "<br>");

Remarks

In order to cache a response, the following criteria need to be met:

• Caching must be explicitly enabled by a page directive or by the caching API.

• Caching must have an expiration policy so that the kernel knows when to discard it.

• Caching cannot have any variable headers or parameters.

• The request must not require any authentication.

This property is relevant only when Internet Information Services (IIS) version 6.0 or later is installed.
