I am using CORS POST request with everything taken care as given @http://www.html5rocks.com/en/tutorials/cors/
Server sets Response header to: \'Access-Control-Allow-Ori
I have seen this error in IE11:
SEC7118: XMLHttpRequest for http:// required Cross Origin Resource Sharing (CORS)
Adding the following to my .htaccess
fixed it:
SetEnvIf Origin ":" IS_CORS
Header set Access-Control-Allow-Origin "*" env=IS_CORS
