The best way to interaction between parent window and iframe is postMessage. Browsers support: FF3+, IE8+, Chrome, Safari(5...), Opera10+. Take a look for documentation: https://developer.mozilla.org/en-US/docs/Web/API/Window.postMessage

/*Parent*/
iframe.contentWindow.postMessage('some content', "http://child-domain");



/*Child*/
window.addEventListener("message", function(e){
console.log(e.data)
//set cookies or other
}, false);
