CORS not working on Chrome

Question

I've set up Cross-Origin Resource Sharing on a server (Jetty using the CrossOriginFilter) and it works perfectly on IE8 and Firefox. On Chrome, it just ... doesn't.

  $.ajax({ url : crossOriginURL,     type : "GET",     error : function(req, message) {         alert(message);     },     dataType :  "json" } ); 

The error function is invoked, with the helpful message "error". It seems to be making the request, but without any of the headers you'd expect. If the URL is from the same origin, it works fine.

I have solved my problem this way:

Add this to your PHP Code:

header("Access-Control-Allow-Origin: *"); header("Access-Control-Allow-Credentials: true "); header("Access-Control-Allow-Methods: OPTIONS, GET, POST"); header("Access-Control-Allow-Headers: Content-Type, Depth, User-Agent, X-File-Size, X-Requested-With, If-Modified-Since, X-File-Name, Cache-Control"); 

Or add these headers to your response.

Problem: The browsers ask to the server for options before your main request, to check if the site has the option to allow comunication with different origin, and then if yes, they do your POST or GET request.

EDIT: Try this (without your hack) to see if you're receiving data...

$.ajax({ url : crossOriginURL,     type : "GET",     error : function(req, message) {         alert(message);     },     success : function(data) {         alert(data);     },     dataType :  "text"} );
