I also had trouble with this, not just in IE but also in Chrome and Safari using jQuery 1.6.2. This solution appears to work as intended in all browsers I've tried (Chrome, Safari, IE, Firefox).

$.ajax({
    headers: { 
        Accept : "text/plain; charset=utf-8",
        "Content-Type": "text/plain; charset=utf-8"
    }
    data: "data",
    success : function(response) {
        ...
    }
})

For me it work like this :)

apiReq = $.ajax({
    url        : APP.apiUrl + path,
    method     : method || 'get',
    //cache    : false,
    crossDomain: true,
    contentType: contentType || 'application/json',
    dataType   : 'json',
    processData: false,
    data       : values || null,
    success    : success || APP.onSuccess,
    error      : error || APP.apiError
});

I'm trying this:

$.ajax({
headers: {
Accept : "text/javascript; charset=utf-8",
"Content-Type": "text/javascript; charset=utf-8"
},
type: "GET", url: rootURL, dataType: "jsonp",
beforeSend: function(xhr){
xhr.setRequestHeader('Access-Control-Allow-origin', 'true');
},
//jsonp: false,
//jsonpCallback: 'eval',
success: function(data) {
console.log(data);
},
error: function(jqXHR, msg, erro){
console.log(erro);
}
});

But the request is going:

Accept: /

HELP!!

hello i think only the server can set 'Access-Control-Allow-origin' @lazaropj
