Detailed Description

Singleton Object that handles a binary cache on top of the http cache management of kio.

A limited number of HTML pages are stored in this cache. This cache is used for the history and operations like "view source". These operations always want to use the original document and don't want to fetch the data from the network again.

It operates completely independent from the kio_http cache.
