Remarks
Post a message to main frame. The embedded application can restrict the messages to a certain target origin. See HTML5 spec for how target origin can be used.
A target origin can be set as a wildcard ("*"). However this is not recommended. See the page above for security issues.
Content loaded via #loadData(String,String,String) will not have a valid origin, and thus cannot be sent messages securely. If you need to send messages using this function, you should use #loadDataWithBaseURL(String,String,String,String,String) with a valid HTTP or HTTPS baseUrl to define a valid origin that can be used for messaging.
