Is possible to connect using Javascript client to more than one SignalR servers?

For example:

<script type="text/javascript">
    $.connection.hub.url = '';
    var server1Hub = $.connection.server1Hub;

    $.connection.hub.start().done(function () {

    });

    // i need to connect to server2
    $.connection.hub.url = '';
    var server2Hub = $.connection.server2Hub;

    $.connection.hub.start().done(function () {

    });
</script>

Trying to connect (again) the second time gives me an error:

'server1Hub' Hub could not be resolved.

Can i create two instances of $.connection ? Obviously i think modifying the same connection can create many issues.

Using different $connection:

var connection1 = $.connection('/first');
connection1.start();

var connection2 = $.connection('/second');
connection2.start();

Subscribing on multiple hubs:

var connection1 = $.hubConnection("'http://server1/signalr");
var connection2 = $.hubConnection("http://server2/signalr");

var Hub1= connection1.createHubProxy('Hub1');
var Hub2= connection2.createHubProxy('Hub2');

connection1.start();
connection2.start();

Read more here: here at section Define method on client (without the generated proxy, or when adding after calling the start method)

Thank you SilentTremor. You saved me a lot of time.

If you are working with generated proxies then you can use something like:

var Hub1 = connection1.createHubProxies().<your hub class>

Replace with your own class. Then just get access to all server functions from Hub1. Example:

var Hub1 = connection1.createHubProxies().Chat;
...
Hub1.addMessage(name, message);
