Multiple SignalR JS proxy instances, multiple callbacks

Question

Is it possible to create multiple instances of the SignalR proxy server or implement a function callback once?

If I write something like:

var obj1 = function() 
{
    var someHub = $.connection.someHub;
    var self = this;

    someHub.client.someFunction = function(item){

        //do something
    };
}

var obj2 = function() 
{
    var someHub = $.connection.someHub;
    var self = this;

    someHub.client.someFunction = function(item){

        //do something else
    };
}

Which incarnation someFunctionwould be triggered? Is it possible to implement the same function twice and execute both implementations?

Answer 1

var someHub = $.connection.someHub;

someHub.on('someFunction', function (item) { /* ... */ });
someHub.on('someFunction', function (item) { /* ... */ });

In the above code, both callbacks will be called in the order in which they were attached for each call Clients.*.someFunctionon the server.
