well thanks for the informations....
so there is also now way to "wait" for an update, like that the PHP script or what so ever is "sending" an information to the client that there is an data update. and when this signal is coming you make a ajax request?
(my game is waiting)
(the other make a move or something, this update my data on the server)
(the server is sending an "ping" to my game)
(no my game check for this new data update)
so you don't have to make every x second a request!
is there a way to do something like this?
i hope you where understanding everything ;)
