webkit_web_context_new_ephemeral ()

WebKitWebContext *
webkit_web_context_new_ephemeral (void);

Create a new ephemeral WebKitWebContext. An ephemeral WebKitWebContext is a context created with an ephemeral WebKitWebsiteDataManager. This is just a convenient method to create ephemeral contexts without having to create your own WebKitWebsiteDataManager. All WebKitWebViews associated with this context will also be ephemeral. Websites will not store any data in the client storage. This is normally used to implement private instances.

Since: 2.16

webkit_web_context_new_with_website_data_manager ()

                                gboolean allowed);

Set whether automation is allowed in context . When automation is enabled the browser could be controlled by another process by requesting an automation session. When a new automation session is requested the signal “automation-started” is emitted. Automation is disabled by default, so you need to explicitly call this method passing TRUE to enable it.

Note that only one WebKitWebContext can have automation enabled, so this will do nothing if there's another WebKitWebContext with automation already enabled.

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.

                                WebKitNetworkProxySettings *proxy_settings);

Set the network proxy settings to be used by connections started in context . By default WEBKIT_NETWORK_PROXY_MODE_DEFAULT is used, which means that the system settings will be used (g_proxy_resolver_get_default()). If you want to override the system default settings, you can either use WEBKIT_NETWORK_PROXY_MODE_NO_PROXY to make sure no proxies are used at all, or WEBKIT_NETWORK_PROXY_MODE_CUSTOM to provide your own proxy settings. When proxy_mode is WEBKIT_NETWORK_PROXY_MODE_CUSTOM proxy_settings must be a valid WebKitNetworkProxySettings; otherwise, proxy_settings must be NULL.

webkit_web_context_get_favicon_database
                               (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
                               (WebKitWebContext *context,
                                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_cache_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
                               (WebKitWebContext *context);

Specifies a process model for WebViews, which WebKit will use to determine how auxiliary processes are handled.

WEBKIT_PROCESS_MODEL_MULTIPLE_SECONDARY_PROCESSES will use one process per view most of the time, while still allowing for web views to share a process when needed (for example when different views interact with each other). Using this model, when a process hangs or crashes, only the WebViews using it stop working, while the rest of the WebViews in the application will still function normally.

WEBKIT_PROCESS_MODEL_SHARED_SECONDARY_PROCESS is deprecated since 2.26, using it has no effect for security reasons.

This method **must be called before any web process has been created**, as early as possible in your application. Calling it later will make your application crash.

Sets initial desktop notification permissions for the context . allowed_origins and disallowed_origins must each be GList of WebKitSecurityOrigin objects representing origins that will, respectively, either always or never have permission to show desktop notifications. No WebKitNotificationPermissionRequest will ever be generated for any of the security origins represented in allowed_origins or disallowed_origins . This function is necessary because some webpages proactively check whether they have permission to display notifications without ever creating a permission request.

This function only affects web processes that have not already been created. The best time to call it is when handling “initialize-notification-permissions” so as to ensure that new web processes receive the most recent set of permissions.

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.
