Attach script load/readystatechange before script.src in cross-site ajax request

[dmethvin]

IE can sometimes fire ready right after script.src is set if the file is in cache. Just need to move the set below the attach of the handlers.

This sounds interesting but needs extensive testing across all supported browsers (which with this caching issues is a pain) as, judging by the comments on the blog post, this may not be fool proof and could start failing in other browsers other randomly.

While I would understand the behaviour for Image, I seriously doubt this would apply to script tags seeing as they're not loaded before the tag is injected into the document afaik. I may be wrong but I never ran into the problem before. Do you have tests to back this up, Dave?

In creating some tests I don't see it failing in IE6 or IE8 so I will close this.
