Far from me the idea of relaunching the debate on multi-user dashboard. I understood that it was not made for !  
That said, my application is not fully multi-user: I have 2 user groups. An admin type will have access to all functions. The other no: I just have 3 buttons to disable.  
To do this, is it possible one way or another, to retrieve the address appearing in the address bar of the web browser: thus, I will be able to retrieve the user's socketid and carry out my routing in function.

Thanks for your help

If you disable 3 buttons for the 1e user, then the will also be disabled for the other users.

I'm using the ip address of a specific user (tablet living room vs tablet bed room) to do some different actions. For me, load a different floorplan for the different tablets as default.

With **ui\_control** you can get **Getchanges** and filter the ip address out with **msg.socketip**.

Maybe this can help you, have fun.

You can get the browser url as below.  
add one for each tab, when tab loads the url will be sent in the payload.

```auto

```

```auto
<script>
(function(scope) {
    scope.send({payload: window.location.href});  
})(scope);
</script>

```

[edit]  
you can also get the port , hostname and more if required

Thank you for your reply. Your idea is indeed interesting. My problem is that a priori, I can not know the fixed IP addresses of the computers to be connected. But I retain your solution for possible future projects.

@E1cid suggestion will return the IP address in `msg.socketip` of whatever device connects to the dashboard. Here is what I get connecting from an iPhone:
