    WEBKIT_CACHE_MODEL_DOCUMENT_VIEWER,
    WEBKIT_CACHE_MODEL_WEB_BROWSER,
    WEBKIT_CACHE_MODEL_DOCUMENT_BROWSER
} WebKitCacheModel;

Enum values used for determining the WebKitWebContext cache model.

webkit_web_context_get_default ()

WebKitWebContext *  webkit_web_context_get_default      (void);

Gets the default web context

webkit_web_context_get_cache_model ()

WebKitCacheModel    webkit_web_context_get_cache_model  (WebKitWebContext *context);

Returns the current cache model. For more information about this value check the documentation of the function webkit_web_context_set_cache_model().

webkit_web_context_set_cache_model ()

void                webkit_web_context_set_cache_model  (WebKitWebContext *context,
                                                         WebKitCacheModel cache_model);

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. The default value is WEBKIT_CACHE_MODEL_WEB_BROWSER.

webkit_web_context_clear_cache ()

void                webkit_web_context_clear_cache      (WebKitWebContext *context);

Clears all resources currently cached. See also webkit_web_context_set_cache_model().

Requests downloading of the specified URI string.

webkit_web_context_get_cookie_manager ()

WebKitCookieManager * webkit_web_context_get_cookie_manager
                                                        (WebKitWebContext *context);

When the operation is finished, callback will be called. You can then call webkit_web_context_get_plugins_finish() to get the result of the operation.

webkit_web_context_get_plugins_finish ()

GList *             webkit_web_context_get_plugins_finish
                                                        (WebKitWebContext *context,

The locale string typically is in the form lang_COUNTRY, where lang is an ISO-639 language code, and COUNTRY is an ISO-3166 country code. For instance, sv_FI for Swedish as written in Finland or pt_BR for Portuguese as written in Brazil.

You need to call this function with a valid list of languages at least once in order to properly enable the spell checking feature in WebKit.

WebKitURISchemeRequestCallback ()

void                (*WebKitURISchemeRequestCallback)   (WebKitURISchemeRequest *request,

webkit_web_context_register_uri_scheme ()

void                webkit_web_context_register_uri_scheme
                                                        (WebKitWebContext *context,

                                                         gpointer user_data);

Register scheme in context, so that when an URI request with scheme is made in the WebKitWebContext, the WebKitURISchemeRequestCallback registered will be called with a WebKitURISchemeRequest. It is possible to handle URI scheme requests asynchronously, by calling g_object_ref() on the WebKitURISchemeRequest and calling webkit_uri_scheme_request_finish() later when the data of the request is available.
