@@ -91,15 +91,21 @@ This is the routing. You need to add the routes in your index.php file with :
   $route->put ("home", function () { echo "YESY"; });
   $route->delete ("home", function () { echo "YESY"; });
 
-The definition match on the HTTP method (GET,POST,PUT or DELETE).
+The definition match on the HTTP method (GET,POST,PUT or DELETE). It can be
+surcharged by using the _METHOD variable in POST method, with the wanted method
+to use.
 The routes are read sequentially. The first which match the class/method wins.
+You should carrefully order the rules.
+Add the debug on routing with 
+  $route->debug=TRUE;
+to help to see the matches.
 
 We can use some variables to be passed to the called function :
   $route->get ("home3/{plo}/{str}", function ($str, $plo) {echo "$str $plo";});
 
 There is a special action named "redirect" in the "route" class. It provide the
 capability to re-route the Web browser to another page. Put in action :
-  array ("route", "redirect", "nextPage/", FALSE),
+  function () use ($route) {$route->redirect("/home4", FALSE);}
 If the URL match the requested search, the Web browser will load immediately a
 new page named "nextPage/". The FALSE will be change in case of modular
 application (see the MODULAR APPLICATION chapter)
