Ajax stops working after changing domain name in internet explorer 9

Question

We are developing a mobile site using html5, jQuery(1.8.2) and jQuery mobile while making jQuery ajax calls (get and post).
After we changed our domain name, we are getting "access denied" for ajax calls on ie9.
We tried to include jquery.iecors.js. But still we are getting the same error.Is there any resolution for this?

Sample Code:

$.support.cors = true;

$.ajax({
    cache: false,
    async: true,
    crossDomain: true,
    timeout: 600000,

    url: baseUrl + '/SmartTouch/restServices/PrefferedHotels',
    type: 'GET',

    beforeSend: function (xhr) {
        xhr.setRequestHeader("Authorization", "Basic " + myencoded);
    },
    contentType: "application/x-www.form-urlencoded; (http://www.form-urlencoded;) (http://www.form-urlencoded;) charset=UTF-8",
    success: function (data) {

        alert("success");
    },
    error: function (jqXHR, textStatus, errorThrown) {


        alert("error!!::" + JSON.stringify(jqXHR));

        alert('response: ' + jqXHR.responseText);
        alert('code: ' + jqXHR.getResponseHeader('X-Subscriber-Status'));
        alert("textStatus " + textStatus);
        alert("errorThrown " + errorThrown);

    }
});

Edited:

beforeSend: function (xhr) {
    xhr.setRequestHeader("Authorization", "Basic " + myencoded);
    xhr.setRequestHeader("Access-Control-Allow-Origin", "*");
    xhr.setRequestHeader("Access-Control-Allow-Methods", "POST,GET,OPTIONS");
},
contentType: "application/x-www.form-urlencoded; (http://www.form-urlencoded;) (http://www.form-urlencoded;) charset=UTF-8",
success: function (data) {
    alert("success");
},
error: function (jqXHR, textStatus, errorThrown) {
    alert("error!!::" + JSON.stringify(jqXHR));

Answer 1

This kind of Content-Type looks strange:

application/x-www.form-urlencoded; (http://www.form-urlencoded;) (http://www.form-urlencoded;) charset=UTF-8"

I can imagine the IE has as problem with it.

Try the proper one:

application/x-www-form-urlencoded; charset=UTF-8
                 ^-- notice: no dot!

It's also possible for the IE to have problems with the authorization. Maybe myencoded is out of the scope or not filled correctly. Debug this variable and have a look at this question: Authorization through setRequestHeader
