2.1.5 Full Web page versus fragment caching
A fragment is a part or all of a rendered HTML page. Although a whole page may not be "cacheable," it may contain sections of varying cacheability that can be separated into fragments and then cached independently. Any content that can be independently requested can be cached. This means that a fragment cannot depend on any information placed in its request scope by its parent or from other fragments. That means, if the child object gets invalidated, the child object can be executed on its own.
