Hi, I am thinking of a server based(triggered) communication. Such that if any change in data the server sends the info to the client and the change is reflected in the client side application. Only that part of client side changes where the change has to be updated.(Not the whole client page). I know all this sounds very ideal and there must be lot of people already working on smthing similar. I am looking for resources/implementations of the same using php. Even articles that discuss such an architecture wud b great! Thanks, Richa PHP Data object relational mapping generator http://www.metastorage.net/ Yahoo!
