@mzabriskie if the PR looks good can you have it merged?

[ldabiralai]

Good job! Any news on when this'll be merged?

Looking to use it in a project without having to reference the commit hash.

@mzabriskie can we have this merged? we are waiting to use this feature in our project.

Sorry, I thought that I had replied to this already.

A couple changes need to be made, but overall I like the solution.

• Don't commit the dist/ files
• Resolve merge conflicts (probably just rebase on master)
• Don't make XDomain a config option. This should be transparent to the user. Let's have axios handle the logic internally.

// This would go at the top of lib/adapters/xhr.js
var isURLSameOrigin = require('./../helpers/isURLSameOrigin');

// Slight modification to your code
var adapter = (XMLHttpRequest || ActiveXObject);
var loadEvent = 'onreadystatechange';
var xDomain = false;

// For IE 8/9 CORS support
if (!isURLSameOrigin(config.url) && window.XDomainRequest) {
  adapter = window.XDomainRequest;
  loadEvent = 'onload';
  xDomain = true;
}

There was a failing test on master when you merged. I have fixed the test. Please try merging master into your branch again.

Done!
