As per w3c spec http://www.w3.org/TR/XMLHttpRequest/#the-send-method, section 4.7.6(8), readystatechange event needs to be called with the same state for asynchronous XMLHTTPRequest once the Send() flag is set. Looks like this is not happening with webkit. Do we need a fix for this ?

Created attachment 125016 [details] Simplified test case Simplified test case showing the sequence of state when readystatechange event is fired. Webkit browsers fires readystatechange event with [1,2,3,4] (OPENED, HEADERS_RECEIVED, LOADING, DONE) whereas Firefox and IE fires with states [1,1,2,3,4]. As per spec, readystatechange event is supposed to be fired when Send() is called for asynchronous request but webkit does not do that. I will create a patch if we agree to add this.
