Cross Domain Message Passing using Iframe

Submitted by Mabaloo » Due to security restrictions of a web browser, passing messages in a cross domain environment is not that straightforward as it is in a uni-domain environment. A browser will not let any AJAX requests to pass through between two different domains, similarly two frames, open on two different domains cannot communicate with each other, and cannot access the DOM, or the JavaScript or the Cookies. How then can you pass information between two different domains ?
