Cross-domain data exchanges for web application

Today, most modern web applications contain the combination of information and presentation from more than one server in order to make the web application more interesting and delivering acceptable performance. Thus, Cross-Domain communication is used to enable those servers to communicate and exchanging data to each other. In this paper, a survey has been made on some available techniques of Cross-Domain communication in order to be applied in a specific system, which is a real time web application system. The techniques included were chosen based on the current practice of most developers. A signalling based experiment on newly emerged techniques - post Message and CORS, besides Browser Plugin technique was also conducted. All these techniques have been compared to each other to identify the suitability of the techniques in order to be implemented in real time web application based on these requirements; functionalities separation, process invisibility, and data size independent.
