US Patent 8209706 Inter-frame messaging between different domains

Cross-domain communication between a parent web page hosted in a parent domain and a child web page hosted in a different child domain is provided. Upon downloading the parent page and child page into a client's web browser, an IFM-channel connection can be established within the browser between the parent page and child page, which can be used to bidirectionally communicate text-based messages containing commands and HTML content directly between the parent page and child page. Additionally, an XML-channel connection can be established within the browser between the parent page and child page, which can be used to bidirectionally communicate text-based messages containing HTTP commands and XML content directly between the parent page and child page. This cross-domain communication of messages takes place completely within the browser.
