Ahhhh, after some investigation, looks like what im doing is
initiating an asynchronous request to the server, and then not waiting
long enough for the reply, hence why im getting the reply whenever i
make the second request....
Can anyone tell me how i can make sure i get the reply ive asked for?
what am i missing here?
Thanks,
John
