URL 1:- https://my.mysite.co.in

URL 2:-https://axxxx.mysite.co.in

ffp-resources.js:1 Uncaught SecurityError: Blocked a frame with origin "https://my.mysite.co.in" from accessing a frame with origin "https://my.mysite.co.in". The frame requesting access set "document.domain" to "mysite.co.in", but the frame being accessed did not. Both must set "document.domain" to the same value to allow access.
