There are several way to resolve AJAX Cache Issue:

1. In server side, we can add this one:
   header(“Cache-Control: no-cache, must-revalidate”);
2. When sending AJAX request, we can add: anyAjaxObj.setRequestHeader(“If-Modified-Since”,“0”);
3. When sending AJAX request, we can add: anyAjaxObj.setRequestHeader(“Cache-Control”,“no-cache”);
4. Add new parameter after URL, for example: “?fresh=” + Math.random(); or “?timestamp=” + new Date().getTime();
5. Use “post” instead of “get”. It is not recommended.

For jquery:

$.ajax( cache: false, url: 'http://myurl', data: {} );

This will work for this particular request. If you want to expand the scope of this setting to all AJAX requests, you can set it on the global AJAX configuration:

$.ajaxSetup({ cache: false });
