ie jquery ajax json,internet explorer - jQuery and Ajax with json - fails in IE - Stack Overflow

I'm using jQuery (1.7.0) to make a json/ajax call to Spotify. The following code works fine in Chrome and Firefox, but causes an error (Error: Access is denied.) in IE.

$.ajax({

url: 'http://ws.spotify.com/lookup/1/.json',

type: 'GET',

dataType: 'json',

cache: true,

data: {

uri: "someartist",

extras: "album"

},

success: successfn,

error:function(xhr, status, errorThrown) {

alert("networking error: "+errorThrown+'\n'+status+'\n'+xhr.statusText);

}

});

The success function is called in Chrome and FF, but the error function is called in IE with the above message. I have set cors to true: jQuery.support.cors = true;.

It works on Chrome and FF both locally and on my server, it works in IE locally but not on the server. Changing cache: false causes problems at the spotify end - doesn't line additional parameters, so I get a "bad request" error.

Grateful for any pointers.

Thanks
