/**
 * SECTION: e-source-webdav

 * @short_description: #ESource extension for WebDAV settings
 *
 * The #ESourceWebdav extension tracks settings for accessing resources
 * on a remote WebDAV server.
 *
 * This class exists in libedataserver because we have several
 * WebDAV-based backends.  Each of these backends is free to use
 * this class directly or subclass it with additional settings.
 * Subclasses should override the extension name.
 *
 * The #GUri is parsed into components and distributed across
 * several other built-in extensions such as #ESourceAuthentication
 * and #ESourceSecurity.
 *
 * Access the extension as follows:
 *
 * |[
 *   #include <libedataserver/libedataserver.h>
 *
 *   ESourceWebdav *extension;
 *
 *   extension = e_source_get_extension (source, E_SOURCE_EXTENSION_WEBDAV_BACKEND);
 * ]|
