Hi all, I have a problem on ajax error event handler with non existing file on url parameter -> 404 feedback ( the other event success / complete works fine all browser ). With the code below, FF and OPERA 9.27 fire error event but IE 7 and SAFARI 3.1.1 not.

Thanks in advance, i start to look in your code ...

$.ajax (
	 type: 'POST',
	 url: 'a file that do not exist',
  	 dataType: 'HTML',
         data :'test=1',
	 success: function (data, textStatus) {	
         error: function (XMLHttpRequest, textStatus, errorThrown) {	 
         complete : function(XMLHttpRequest, textStatus) {

Adding "|| xhr.status == 404" fix the problem, don't forget to add it in future release ;-)

Oups sorry guys that still don't work ( forget to update some cache ), if i check the header on requested file that don't exist by using i have a nice and normal 302.

If i display the xhr.status but adding alert('xhr status = '+xhr.status); inside Jquery a have this result :

FF xhr.status = 302

OPERA xhr.status = 0

IE xhr.status = 200

SAFARI = no display at all

Is it possible that

cache: true
(the default) is part of the reason?

Fixes #2994. Not finding a transport now fires the error callbacks and doesn't make ajax return false. Had to revise how jsonp and script prefilters & transports work (better separation of concerns). Also took the opportunity to revise jXHR getRequestHeader and abort methods and enabled early transport garbage collection when the request completes.
