+ * TUrlManager class
+ *
+ * TUrlManager is the base class for managing URLs that can be
+ * recognized by PRADO applications. It provides the default implementation
+ * for parsing and constructing URLs.
+ *
+ * Derived classes may override {@link constructUrl} and {@link parseUrl}
+ * to provide customized URL schemes.
+ *
+ * By default, {@link THttpRequest} uses TUrlManager as its URL manager.
+ * If you want to use your customized URL manager, load your manager class
+ * as an application module and set {@link THttpRequest::setUrlManager THttpRequest.UrlManager}
+ * with the ID of your URL manager module.
