Can I load a web worker script from an absolute URL?

I haven\'t been able to get something like this to work:

var myWorker = new Worker(\"http://example.com/js/worker.js\");

In my Firebug cons

For those that don't know, here is the spec for Web Worker: http://www.whatwg.org/specs/web-workers/current-work/

And a post by John Resig: http://ejohn.org/blog/web-workers/

Javascript, generally, can't access anything outside of the url that the javascript file came from.

I believe that is what this part of the spec means, from: http://www.w3.org/TR/workers/

4.2 Base URLs and origins of workers

Both the origin and effective script origin of scripts running in workers are the origin of the absolute URL given in that the worker's location attribute represents.
