9883	Allow users to respond to other ajax event states.	hungerandthirst@…	jaubourg	"The jQuery docs explicitly state that ""No onreadystatechange mechanism is provided, however, since success, error, complete and statusCode cover all conceivable requirements.""

Frankly I think that's limiting users unnecessarily. What if I want to respond to something when I get headers back? What if I want to know when I start receiving content back from the server?

An excellent example of this is using jQuery for bandwidth testing. Without a way to detect when I initially receive content back from the server (not just beforeSend), I will also include any delay spent waiting for the server to respond.

I've added support for the RECEIVE_HEADER and LOADING event as per the XMLHttpRequest specs in [https://github.com/jquery/jquery/pull/438/ this pull request].

I would also like to see support for onreadystatechange as well since those are valuable states that we are only limiting ourselves and losing value by not tracking."	feature	assigned	low	None	ajax	git		1.9-discuss
