RequireJS Caching

Question

We are having some trouble with RequireJS not grabbing a fresh copy each time it is requested. We have used the following without success:

require.config({
    urlArgs: "bust=" + (new Date()).getTime()
});

When viewing the network log, the page is loaded with the argument appended to the URL, however if the same page is called again, it doesn't appear in the network log at all, so it is coming from the cache somehow.

If anyone has any ideas, it would be greatly appreciated.

Thanks, Ryan.

The 'page' is loaded, or the module (JS) is loaded with the argument appended? — Paul Grime, Apr 04 '13 at 07:07
Or Math.random() which is shorter and a bit faster. http://jsperf.com/speedcomparison — Vlad Tsepelev, Jul 24 '13 at 12:51

This jsfiddle example shows urlArgs working.

require.config({
    urlArgs: "bust=" + (new Date()).getTime(),
    paths: {
        "jquery": "http://code.jquery.com/jquery-1.9.1"
    }
});

require(["module", "jquery"], function (module, $) {
    console.log($.fn.jquery);
    console.log(module, module.config());
});

With this output:

1.9.1
Object { id="_@r5", uri="./_@r5.js?bust=1365059426478", config=function()} Object {}

And the Net panel in Firebug shows a fresh version of jQuery downloaded each time.
