The middleware keeps the urls of a CakePHP website consistent by preventing, for example,
an action in a given controller from being accessed in a way other than as defined in the routes.
The action index in the UsersController, for example, can be accessed via two different urls: (1) /users or or (/users/index) the middleware prevents this by making sure that the correct url (in this case /users) is the one used.
Step 1) Download the UrlConsistenceMiddleware.php and move it to /src/Middleware/UrlConsistenceMiddleware.php Step 2) Open your /src/Application.php and add the UrlConsistenceMiddleware to your middleware queue but make sure that it is placed immediately after the RoutingMiddleware. Step 3) Optional - clear the cache. You can do this via cmd: browse to your app directory and run this command: bin/cake cache clear_all
