This PR is incredibly solid.

This PR should henceforth be referred to as the mother of all PRs.

@guille Thanks you!!

You need to provide a way to turn this off as xdomainrequest is severely flawed. (Not sending cookies etc)

@3rd-Eden Thanks to your comment! I sent a PR to README (#332). Instead of adding a new option, I'd recommend you use forceJSONP.

In #217 we removed this functionality for a reason. I personally would rather see a working connection with a loading bar then a dead connection.

@3rd-Eden I see your point. I fixed not to use XDR when crossing scheme in my PR. So the first flaw in #217 is not a problem. So the other one of not sending cookie is the main point then?

Should I create a new PR not to use XDR as default and provide an option to enable it?

OK, I closed #332 then.

Using the forceJSON flag also prevents the use of regular XHR, I wouldn't really call this a solution.

OK, I did. #333
