Cache-style middleware not working

[rblstr]

Following the https://github.com/englercj/resource-loader/blob/master/src/middlewares/caching/memory.js middleware example, the following code should populate resource.data and not perform a network request. However, calling resource.complete() doesn't seem to stop the load from happening.

var Loader = require ('resource-loader');

var loader = new Loader();

var cache = {
    'example.json': {
        'test': 'one, two'
    }
};

loader
    .add('example.json')
    .before(function (resource, next) {
        if (cache[resource.url] != null) {
            resource.data = cache[resource.url];
            resource.complete();
        }

        console.log('calling next');
        next();
    })
    .load(function (loader, resources) {
        console.log('complete');
    });

I would expect this to simply call the complete callback with the cached data in the response.data, however it still tries to perform the web request.

Is the example code out of date? Or is it no longer possible to complete loads in the before middleware? I can't see anything in the code to check if the resource load was completed before making the load request.
