+In the case of a **GET** request with the default configuration, the mapping
+between controller/methods and URIs is as follows:

+============================ ============================ =============================================
+Controller/Method            URI                          Description
+============================ ============================ =============================================
+``Home::getIndex()``         /                            The default controller and the default method.
+``Blog::getIndex()``         /blog                        The default method.
+``UserProfile::getIndex()``  /user-profile                The default method.
+``Blog::getTags()``          /blog/tags
+``Blog::getNews($id)``       /blog/news/123
+``Blog\Home::getIndex()``    /blog                        Sub-directory ``Blog`` and the default
+                                                          controller and the default method. If there
+                                                          is ``Blog`` controller, it takes precedence.
