jQuery.support.cors = true about backbone.crossdomain

Hey aroc,

Thanks for the kind words.

The intent there was to defer to jQuery.support.cors to figure out whether a particular browser would support cors. This should be true for most modern browsers and false for IE7/8/9 (and any other browser that doesn't support cors of course).

It's not intended to be set, only read, it's a result of jQuery's internal test to see whether a given browser supports cors. See: http://vq.io/12fvcQj

$.support.cors contains the result of a test that tests whether or not the current browser supports cors. changing it doesn't make the browser support cors.

If the browser does not support cors, then my library tries to use IE's XDomainRequest object to make the cors request. Setting it to true is just overriding that check within jQuery so it always returns true which is bound to have some funny side effects.

So I'm a bit confused at how setting it is making things work for you. The only result in doing so would be to bypass use of IE's magic cross domain request object in my library, thereby making any cross domain requests on IE fail.

In any event, if you can give me a bit more info, a code snippet, or a pull request I can look into this, otherwise it sounds like you probably want to check a bit more about your IE support as I suspect it's probably not working as expected.

Hey @victorquinn - you're absolutely right about the $.support.cors thing. I still remained unable to get this plugin working without it, so I switched to using this project: https://github.com/MoonScript/jQuery-ajaxTransport-XDomainRequest
