angularjs routing - stay on page and do nothing on "otherwise" method
<p>I need to set Angularjs routing to do nothing on "otherwise" method. </p>

<pre><code>var townApp = angular.module('townApp', ["ngRoute"]);
townApp.config(function($routeProvider){
    $routeProvider
        .when("/dashboard", {
            templateUrl : "/profile/dashboard/"
        })
        .when("/payments", {
            templateUrl : "/profile/payments/",
        })
        .otherwise(
            /* DO NOTHING.*/
        )
});
</code></pre>

<p>Right now, it cleans the ng-view directive upon changing url to an undefined one and that's not what I need. 
How can I make it stay on the same page and do nothing?</p>
