Locally hosted YUI 3 over https without multiple requests

// Step 1. Create a module config object to pass to the YUI constructor
var myModules = {
    bacon: {
        path: '/path/to/rollup/file.js', 
        supersedes: ['list','of','the','concated','modules'],
        rollup: 3
    }
};

// Step2 . Instantiate your YUI with your module config and use()
YUI({ modules: myModules }).use('list', 'of', 'modules', function (Y) {
    /* all rolled up modules are available and only one https request was made */
});

// Even though only 3 of the modules are being loaded, it'll load the rollup to save the HTTP request.
