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