frontend:
first :add $.support.cors=true; in front of the Ajax code.
seconde: add the crossDomain:true, attribute to the $.ajax.
webconfig:
add the following code to the node <system.webServer>
<httpProtocol>
<customHeaders>
<add name="access-control-allow-headers" value="accept, origin, token,content-type" />
<add name="Access-Control-Allow-Credentials" value="true" />
<add name="Access-Control-Allow-Methods" value="OPTIONS, GET, POST" />

*
* By default, support transferring session cookie with XDomainRequest for IE. The cookie value is by default 'jsessionid'
*
* You can change the session cookie value like this, before including this script:
*
* window.XDR_SESSION_COOKIE_NAME = 'ID';
*
* Or if you want to disable cookie session support:
*
* window.XDR_SESSION_COOKIE_NAME = null;
*
* If you need to convert other cookies as headers:
*
* window.XDR_COOKIE_HEADERS = ['PHP_SESSION'];
*
* To DEBUG:
*
* window.XDR_DEBUG = true;
*
* To pass some headers:
*
* window.XDR_HEADERS = ['Content-Type', 'Accept']
*
