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 encountered SEC7118 when CORS was set up correctly. I verified that the requests were completing with status 200 using the network debugger. So, you can disregard this message if your application is otherwise functioning properly.
