jQuery跨域请求失败“拒绝访问”在IE中

问题描述

Hello There,

My Ajax cross domain request is failing in IE 11 with "Access denied". I have read through several posts regarding this topic, and done below changes but getting same issue.

1)  Call is async=false, dataType='json' and crossDomain, cache is false. 
    These are the prerequisites I have found.
2)  Works in latest Firefox and Chrome.
    jQuery.support.cors is true
  
Why is this failing with Access denied? Any idea? 

I have tried with JSONP and here i am not getting "Acces Denied" error. But problem is, i can able to get the result into success function and the same passing to global variable. when call the global parameter outside of the success function, there it is coming "Undefined". 

 I have read through several posts regarding this issue also. FYR, was followed the below link.
