A small/light script for doing cross-domain, cross-browser ajax requests.

It provides 2 utility methods:

• crossdomain.ajax(options)
• crossdomain.async_load_javascript(path, on_load_callback)

ajax() does cross-domain requests. If it cannot use HTTP Access Control (CORS) available in modern browsers, then it falls back to flensed.flXHR, a Flash-based plugin which provides an alternative implementation for XmlHttpRequest.

But flXHR is heavy and doesn't work on mobile-phones well, so if the browser supports CORS, then it prefers doing that.

async_load_javascript() is used internally for asynchronously loading flXHR, only in case it is needed. It loads a Javascript file, and when done it executes the provided callback. Multiple callbacks provided (by multiple calls done at the same time) are stacked.

If it doesn't work for you, please open a bug-ticket (with details) and I'll love to fix it for you.
