+Suppose we want to redirect not logged in user to login page, which can be done using handling exception in ```app\Exceptions\Handler.php``` class. The purpose of this exception make available is to support full customization. For example you may want to redirect to login page for that user whom don't have right role, or you simply only want to show 403 page.
+```php
+// App\Exceptions\Handler.php;
+use Aammui\RolePermission\Exception\UserNotLogin;
+use Aammui\RolePermission\Exception\RoleDoesNotExist;
+
+....

+        return redirect()->back();
