 * @WEBKIT_CACHE_MODEL_DOCUMENT_BROWSER: A cache model optimized for viewing
 *   a series of local files -- for example, a documentation viewer or a website

 *   This is the default process model, and it should suffice for most cases.

 *   share a process in certain situations. The main advantage
 *   of this process model is that the rendering process for a web view
 *   can crash while the rest of the views keep working normally. This
 *   process model is indicated for applications which may use a number
