$.ajax({
           url: url,
           type: 'POST',
           data: {dataname: details},
           success: function(result){

                 //THIS IS WHERE I AM HAVING PROBLEMS

                 location.href = "http://depressionapp1.westeurope.cloudapp.azure.com/welcome1.html";

                 /* or

                 $.get(url1);*/
