     90  * #WebKitWebView is the central class of the WebKitGTK+ API. It is a
     91  * #GtkWidget implementing the scrolling interface which means you can
     92  * embed in a #GtkScrolledWindow. It is responsible for managing the
     93  * drawing of the content, forwarding of events. You can load any URI
     94  * into the #WebKitWebView or any kind of data string. With #WebKitWebSettings
     95  * you can control various aspects of the rendering and loading of the content.
     96  * Each #WebKitWebView has exactly one #WebKitWebFrame as main frame. A
     97  * #WebKitWebFrame can have n children.

   4187  * webkit_set_cache_model:
   4188  * @cache_model: a #WebKitCacheModel
   4189  *
   4190  * Specifies a usage model for WebViews, which WebKit will use to
   4191  * determine its caching behavior. All web views follow the cache
   4192  * model. This cache model determines the RAM and disk space to use
   4193  * for caching previously viewed content .
   4194  *
   4195  * Research indicates that users tend to browse within clusters of
   4196  * documents that hold resources in common, and to revisit previously
   4197  * visited documents. WebKit and the frameworks below it include
   4198  * built-in caches that take advantage of these patterns,
   4199  * substantially improving document load speed in browsing
   4200  * situations. The WebKit cache model controls the behaviors of all of
   4201  * these caches, including various WebCore caches.
   4202  *
   4203  * Browsers can improve document load speed substantially by
   4204  * specifying WEBKIT_CACHE_MODEL_WEB_BROWSER. Applications without a
   4205  * browsing interface can reduce memory usage substantially by
   4206  * specifying WEBKIT_CACHE_MODEL_DOCUMENT_VIEWER. Default value is
   4207  * WEBKIT_CACHE_MODEL_WEB_BROWSER.
