Request parameters for dataTable parameters for version 1.10+

In previously i'm using Data table version 1.9, i'l get the exact data table parameters from given below, it was work perfectly in version 1.9. request.getParameter("sColumns"); request.getParameter("iColumns"); request.getParameter("iSortingCols"); request.getParameter("iSortCol_0"); request.getParameter("sSortDir_0");

But now i using data table version 1.10+, i'l get these parameters are null, what type of request parameters used in new version instead of these old version keyword parameters.

Please help to solve this issue.
