How to prevent a jQuery Ajax request from caching in Internet Explorer?

If you set unique parameters, then the cache does not work, for example:

$.ajax({
    url : "my_url",
    data : {
        'uniq_param' : (new Date()).getTime(),
        //other data
    }});

Cache-Control: no-cache, no-store

These two header values can be combined to get the required effect on both IE and Firefox

You can disable caching globally using $.ajaxSetup(), for example:

$.ajaxSetup({ cache: false });

This appends a timestamp to the querystring when making the request. To turn cache off for a particular $.ajax() call, set cache: false on it locally, like this:

$.ajax({
  cache: false,
  //other options...
});
