Answer 1

After have understood the @tkone 's explanation...

If you still want to have a dynamic Model.url you always can delay its construction to run time, try this:

window.MyModel = Backbone.Model.extend({
  url: function(){
    return this.instanceUrl;
  },
  initialize: function(props){
    this.instanceUrl = props.url;
  } 
}
