redirection without "server processing page"

what if i want to do it to the whole page ? the thing is : i have a timer that redirect to the same page every min , i dont know where should i put Clients.clearBusy();

In your ZUL page, right after the main window declaration. No need to add something in your view model (or the composer) class:

<window id="mainWindow"> <attribute name="onCreate"> Clients.clearBusy();
</attribute> ... ... </window>

in my case i m using a border layout to include serval pages , i didnt use a window , it will work with aborder layout ? or should i add a window then add this attribut ?

To be honest i have used it only as a window attribute. But i don't think you will have any problem if you wrap your border layout inside a main window. So your zul code should look like: <window> <attribute name="onCreate">....</attribute> <borderlayout>......</borderlayout> </window>
