I want to make a game using java ( really, i want to do it in xna, but first i want to do a prototype still learning xna ), and i got the idea to connect it with php for multiplayer capabilities.

what i want to do is make the server side on php (and use a hosting, or my university server)
there is no need to have something really "fast" ( i have all the game planned, turn based, and part of coding done )

my idea was,

php is running the game flow, the server will be connected to both players, and both players will be connected too.
when players1 make a movement, sends it to the servers, and sends a signal to player2, then, player2 ask the server what have player1 done ( all this is for security issues )

my question is, i was thinking in make java connect php as if it was a web page as any other, but i think that wait for the http response could be really slow, somebody have some tip, another way i can do this?
