Patch: xhr object isn't returned in $.ajax() success callback

[alan.castro]

xhr object is useful to get the headers values.

[alan.castro]

adds xhr object to $.ajax success callback params.

I think you are meant to use the complete callback for that. It does receive the xhr, they have different purposes.

I would also really like to see this change. What i'm after is the ability to check my xhr for specific headers before proceeding with inserting the data returned into the dom. The success callback is really the only place for this that I can tell.

Using the complete() callback is no good for that as it doesn't take the data as a parameter. It's likely I can extract this from the xhr object itself however this seems potentially fragile. It would be much nicer to just have it passed into the success callback directly.

I'd also appreciate this. Like you say, Ariel, the complete and success callbacks have different purposes, and it's in the success callback that i'd like access to the xhr. :)

I also ask why? the error callback contains the XHR object in its signature while the success callback doesn't have it!.
