+1 can we merge this in please.

re-reviewed my code change, and all seems good. this is the correct default behavior for XHRs in the browser. ready to merge.

@kumavis Thanks for re-checking it. I just stumbled across this problem in jsdom with a AJAX library I'm using in some headless test cases. The AJAX library detects support for CORS requests with:

var cors = 'withCredentials' in tmpxhr;

This fails at the moment in jsdom (3.*) because the withCredentials property is not on the XMLHttpRequest object...

@driverdan Please can you merge this into master and build a new release.

📲 come on dan drive it home 🚙

Can we merge this thing @driverdan?

@novabyte for working XHR in jsdom you can use my patch https://github.com/mareksuscak/jsdom-xhr-patch until this gets resolved and merged.

HE LIVES 👻
