Set realm from variable

[so1337]

We're working on messaging app .
First - I login, and then I'm setting the realm name ('realm_'+username);
Now what I'm doing is
$wamp.connection._ options.realm = 'realm_'+$cookies.get('key');
$wamp.open();
But I think it's not good in practice, because sometimes, when wamp is closing socket and reconnecting - the behavior of socket becomes unpredictable , so your only solution is to restart the page.
Is there any method to set custom realm after login and not doin "$wamp.connection._options.realm " this thingy ?
Because there's method setAuthId and It'll be useful to have a method setRealm.

I haven't tested this, but something like this should work:

//create a service that wraps the $wampProvider
.provider('myWamp', function (myWampProvider) {
    this.$get = function ($rootScope, $q, $log, $cookies) {
        var options = {
            url: 'ws://127.0.0.1:8080',
            realm: $cookies.get('key')
        };

        var wp = $wampProvider;
        wp.init(options);
        return wp.$get($rootScope, $q, $log);
    };
})

//in you controller
.controller('MyController', function(myWamp){
    myWamp.open();
})

I actually agree with @so1337 here. Why is the only setting changeable from the outside the authId? Shouldn't all of autobahn's connection options be prone to change, including the URL?
