From a naive perspective, it is not possible for a web page from domain D, to access a URL from another domain E due to security considerations. Several workarounds have been developed, namely the remote script technique. All existing workarounds suffer from significant limitations, such as the unhampered ability to read and write between two different domains.
Say domain D wants to connect to domain E. In a nutshell, the trick is to use DNS to point a sub-domain of D, D_s, to Eâ€™s server. In doing so, D_s takes on the characteristics of E, while also being accessible to D.
