    WEBKIT_CACHE_MODEL_DOCUMENT_VIEWER,
    WEBKIT_CACHE_MODEL_WEB_BROWSER,
    WEBKIT_CACHE_MODEL_DOCUMENT_BROWSER
} WebKitCacheModel;

typedef enum {
    WEBKIT_TLS_ERRORS_POLICY_IGNORE,
    WEBKIT_TLS_ERRORS_POLICY_FAIL
} WebKitTLSErrorsPolicy;

Enum values used to denote the TLS errors policy.

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);

Requests downloading of the specified URI string. The download operation will not be associated to any WebKitWebView, if you are interested in starting a download from a particular WebKitWebView use webkit_web_view_download_uri() instead.

webkit_web_context_get_cookie_manager ()

WebKitCookieManager * webkit_web_context_get_cookie_manager
                                                        (WebKitWebContext *context);

                                                        (WebKitWebContext *context);

Get the WebKitFaviconDatabase associated with context.

To initialize the database you need to call webkit_web_context_set_favicon_database_directory().

webkit_web_context_set_favicon_database_directory ()

void                webkit_web_context_set_favicon_database_directory

                                                         const gchar *path);

Set the directory path to be used to store the favicons database for context on disk. Passing NULL as path means using the default directory for the platform (see g_get_user_data_dir()).

Calling this method also means enabling the favicons database for its use from the applications, so that's why it's expected to be called only once. Further calls for the same instance of WebKitWebContext won't cause any effect.

webkit_web_context_get_favicon_database_directory ()

const gchar *       webkit_web_context_get_favicon_database_directory

Get the directory path being used to store the favicons database for context, or NULL if webkit_web_context_set_favicon_database_directory() hasn't been called yet.

This function will always return the same path after having called webkit_web_context_set_favicon_database_directory() for the first time.

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 or webkit_uri_scheme_request_finish_error() in case of error.
