Handling trailing slashes in angularUI router

There is a link to working plunker

And this is the updated rule definition:

  $urlRouterProvider.rule(function($injector, $location) {

    var path = $location.path();
    var hasTrailingSlash = path[path.length-1] === "https://stackoverflow.com/";

    if(hasTrailingSlash) {

      //if last charcter is a slash, return the same url without the slash  
      var newPath = path.substr(0, path.length - 1); 
      return newPath; 
    } 

  });

And these links will now work properly:

  <ul class="nav">
    <li><a ui-sref="route1">Route 1</a></li>
    <li><a ui-sref="route2">Route 2</a></li>
    <li><a href="#/route1/">#/route1/</a></li>
    <li><a href="#/route2/">#/route2/</a></li>
    <li><a href="#/route1" >#/route1</a></li>
    <li><a href="#/route2" >#/route2</a></li>
  </ul>

The magic could be defined like this: do return changed value if there is a change… otherwise do nothing… see example
